Runner 13
An exhilarating thriller set against a 250-mile foot race in the Sahara Desert, where more than one ultramarathoner will be running for their lives.
Seven years ago, Adri left the running world after a major scandal. She leveled an explosive, and as it turns out career-ending, accusation at one of the world’s most celebrated coaches—and then he died suddenly. Now, after years away from the limelight, she’s ready to race again. Adri is hungry for a challenge, and she’s picked one of the toughest events imaginable: a 250-mile trek through the Sahara Desert organized by a mysterious and famously sadistic race director. It will be a true test of her will and her stamina, proof that after all these years, she can still do it. But she’s also there to get closure on the mysteries that cloud her past. Was her family targeted by one of her coach’s defenders? Was his death due to natural causes?
Adri is determined to finish the race and to find the answers to these long-buried questions. But clarity is hard to come by out in the Sahara’s extreme conditions. And as a number of runners start dropping out, some from the heat and others under more mysterious circumstances, it becomes clear that there’s someone out there in the desert trying to stop anyone from winning—by any means necessary.

An Ultimate Challenge: A 250 mile run in the hot Moroccan desert. Only a select few runners can join- but only upon invitation. This trek also has a few twists to raise the stakes.
We follow Adrienne, the elite runner, on this ultimate quest to return to running but also find out who attempted to kill her son 7 years earlier.
The highs, the lows, the pains and the gains. The exclusive way an ultra runner can compartmentalize while in the pain cave, fascinating. It really makes one wonder the lengths a body and mind can go to complete one of these gruelling races.
McCulloch writes from her own ultra experience and delivers an atmospheric chilly tale.
4⭐️
For those who are intrigued by these ultras, do check out the Barkley Marathons on Netflix.

EEEK!!! BANGER ALERT! BANGER ALERT! Adrenaline-fueled, propulsive, and beyond realistic, Runner 13 was a white-knuckle ride from beginning to end. With two compelling, likable narrators and an exotic locale that came alive on the page, I fell in love with this book in no time at all. Already on my list of authors who I adore, Ms. McCulloch outdid herself this time around. The Queen with a capital Q of survival thrillers, this action-packed race of thrills and chills kept me on the edge of my seat all while dropping one shocking twist after the other. From unexpected appearances of new characters to out-of-the-blue dastardly deeds, I couldn’t get enough of this intense, pitch-perfect novel.
Speaking of those characters, the dual POVs of Adrienne and Stella were simply sublime. While I started out hating one and loving the other, I spent the rest of the novel growing attached to them both. And with a supporting cast of equally spot-on personas, there wasn’t a single weakness to be found within this motley crew of adrenaline-seeking nut jobs—which includes the author. That’s right, she’s also a hardcore ultramarathoner, which surely impacted her ability to bring this world to life. From the runner’s high to the pain cave, I could easily put myself in their shoes as they endured the heart-pumping action and cat-and-mouse chase.
All said and done, if you love extreme environments and bodies dropping like flies, you’re going to want to grab this book now. You see, I literally ignored everything going on around me just to read one more immersive page thanks to the cliffhanger chapters that just would not let me go. Chock full of unbridled suspense, drama-filled scandals, and long-buried secrets, the thoroughly original premise will easily top my list of best books of the year. I mean, there was even a dysfunctional family dynamic and a podcaster angle included for good measure. So, if you’re looking for an under-hyped new release sure to thrill you right from the start, look no further because this book fits that bill to a T. Rating of 5+ stars.

3.5 Stars. Thanks to NetGalley and the publisher for granting my request for the ARC of 'Runner 13' by Amy McCulloch. I was pleased to receive the early digital edition of the book, as I had enjoyed her previous two thrillers, Midnight and Breathless, which featured women facing danger in extreme environments —specifically, an Antarctic journey and mountain climbing. This book is centred on Adrienne, a well-known runner in extreme ultra-marathons.
Seven years earlier, Adri was at the top of her sport in an earlier ultra-marathon. When she crossed the finish line, she learned that her young son was in the hospital. An unknown hit-and-run driver had seriously injured him. Adri had made herself unpopular by blaming a trainer for sexual assault. People thought she was lying, and fans and some racers turned against her. Was the attack on her son in revenge for her scandalous claim? She quit the racing world at the top of her game to be with her son, who has now recovered. Her ex-husband, Pete, is now engaged to Stella, who photographs the extreme races, and is the daughter of Boones, the enigmatic and sadistic race organizer. He is inattentive to Stella, putting all his thoughts and energy into organizing the ultimate in extreme races.
Adri receives an invitation from Boones to participate in the most extreme, exhausting, and difficult upcoming ultra-marathon called Hot and Sandy. The race will begin in Morocco, covering 250 miles through the Sahara Desert. She wants to prove she still has her former endurance and skills, and has been promised the answer to who deliberately injured her son if she finishes the race. Other participants have been told they will have a wish granted, and the winner will receive $500,000. This sets up extreme rivalry, and the competition is fierce.
These experienced runners will face extreme heat, rough trails, slippery terrain, strenuous climbs to mountain passes, hunger, and dehydration with only the equipment they can carry. These are not the only obstacles that one must endure. Boones delights in changing rules, adding unpleasant surprises, and putting the participants in further danger.
The story is told through the perspectives of Adri and Stella, with excerpts from a podcast by Jason and Marc. This is a clever, complex, multi-layered storyline. It immersed the reader in the gruelling, heart-pounding race through the desert landscape. The physical preparation and calm mental state of the racers were of utmost importance. I found the narrative and descriptions to be loose, and tension and suspense would have increased if the writing had been tighter. There were some amazing twists revealed after early hints and clues, as well as deliberate misdirection.
Problems began as soon as Adri arrived at the starting point. Her ex-husband, Pete, was there with Stella, and he was joining the race. He was sent home for failing a drug test, which was foreign to his nature. Once the race begins, Adri feels she is being stalked. The coach she outed as a sexual predator had been killed, and she dreads that her accusing him put her son's life in danger. Several die under mysterious circumstances or receive life-threatening injuries. There seems to be a killer with a gun among the racers and perhaps another with lethal intent. What could their motive be? With the injured and dead piling up, who, if anyone, will be left alive at the finish line?
I recommend Runner 13, as well as the author's two previous and exciting thrillers. The date of publication is July 01/2025.

If The Hunger Games and Into Thin Air had a love child and set it loose in the Sahara, you'd get something like Runner 13. I picked the book up expecting a twisty thriller and got that plus an ultra-marathon through hell. And, I loved it.
Amy McCulloch knows the terrain—both physical and psychological. The 250-mile race across the Sahara is grueling, and she makes you feel every blister, every grain of sand, every ounce of heat. Pain here isn’t just physical—it’s tied to memory, regret, and guilt. The race strips everyone bare, especially Adri, the protagonist, who’s not just running through the heat but from a scandal that scorched her career years ago.
As a runner—one with absolutely no desire to go beyond a marathon—McCulloch had me reconsidering. Her writing on pain, obsession, and endurance is so visceral, so raw, that even the idea of the “pain cave” (which sounds like a horror movie setting) starts to make a strange kind of sense. She captures the mindset of endurance athletes with unnerving precision—but you don’t need to be a runner to get pulled into it.
The race itself feels like a confessional. You meet the other competitors, but more importantly, you watch Adri slowly unravel. There’s something about extreme physical suffering that forces honesty—maybe more than anyone wants. The threads of endurance and reckoning twist tighter with each checkpoint.
And then there’s the killer.
As runners start dropping out—some from heat, others under more suspicious circumstances—you realize this is also a locked-room mystery, just stretched across endless dunes. That blend of psychological thriller and survival epic reminded me of the Hunger Games, but with a grown-up edge. The runners are isolated in a hostile environment, stalked by someone who doesn’t want anyone to finish. The mental and physical toll, combined with the constant threat of death, echoes the arena in Panem. And if Into Thin Air showed the peril of Everest’s cold indifference, Runner 13 trades it for the Sahara’s blistering hostility, where one bad decision could be your last.
And, yes, some plot points do stretch believability. But let’s be honest—this is a story about a 250-mile death race in the desert with a killer on the loose. Hyper-realism isn’t exactly the priority, nor should it be.
If you’re looking for something fast-paced, psychologically sharp, and deeply immersive, Runner 13 hits like a sandstorm: sudden, disorienting, and impossible to ignore. Just don’t be surprised if you find yourself Googling ultramarathons afterward. If so, my advice? Trust no one, hydrate often, and maybe skip the desert death race.

5 Stars for this phenomenal reading experience!
Amy McCulloch completely impressed me with her debut, Breathless, a few years back. Her follow-up, though, left me puzzled and a bit let down, so I approached Runner 13 with cautious expectations. I’m thrilled to report that it not only delivered – it might just surpass Breathless. McCulloch clearly thrives in the realm of expedition-based thrillers, and this one absolutely earned every one of the five stars I’m giving it.
After receiving a surprise, and irresistible, invitation of a lifetime to participate in an Ampersand ultramarathon called Hot & Sandy, Adrienne Wendell (or Adri), is hoping to redeem herself after a scandalous incident seven years ago nearly ended her running career. But this isn’t just any race. As the miles stretch on and the conditions grow more brutal, and one runner after another meet an abrupt end to their race, Adri realizes something far more sinister is at play – and it’s clear not everyone is meant to cross the finish line. As danger lurks in the shadows, she must push past her limits to find both redemption and the answers that have haunted her for years.
McCulloch was clearly in her element writing about ultramarathon running – her firsthand experience shines through on every page. I was blown away by how informative this was – McCulloch doesn’t just tell a gripping story; she pulls you deep into the physical and mental demands of ultramarathon running with incredible detail. I felt like I learned so much while still being completely hooked by the suspense. The novel also weaves in a compelling, multi-layered mystery that slowly unravels through chapters set seven years earlier. This dual timeline added depth and suspense, keeping me completely hooked as the pieces gradually fell into place. Beyond the thrills, this is a powerful story of love, loyalty and the fierce lengths a mother will go to for her child and anyone she loves, I just couldn’t help but love Adri!
What an unforgettable journey this one was! After reading this novel, I’ve gained a whole newfound respect for the sheer grit and resilience of distance runners! After this read, I’m all in for the next adventure McCulloch takes us on!

4.25 stars. This bingeable thriller/whodunnit takes place during a highly competitive race of endurance in the Sahara desert. It kept me on the edge of my seat and second guessing myself to the very end. The audio was fantastic. Really enjoyed this. 🎧 Pub. 7/1/25

As a superfan of IRONMAN, the Olympics, and thrillers (obviously), "Runner 13" by Amy McCulloch had me hitting my runner's high, a euphoric trifecta of adrenaline, ambition, and absolute suspense.
In a grueling 250-mile ultra-marathon across the Sahara, elite runner Adri returns to the sport to reclaim her reputation—only to find herself outrunning more than just competitors. As injuries mount and suspicions rise, she realizes the real danger isn’t the race, but the killer hidden among them.
This novel hit the ground running (literally!) with the disposition and background executed swiftly and effortlessly to deliver the reader to the starting line of this epic race. I was giddy with anticipation for the gun to go off but this race turns into something sinister immediately. The multi-POV elevates the story into a robust web of plot points heading for a collision course at any moment. This adds a layer of juicy suspense knowing we're all headed down a dark and windy path with an array of twists you won't see coming.
Three-quarters in you might hit your wall, feeling as though you are running along side these uber-athletes but out of no where will come your second wind. Ok I am done with the running puns...
But it's all part of the journey to the end of the race and to solve the mystery.
"Runner 13" is the perfect pick for sports fans—that love a murdery vibe—all from the comfort of their couch.

Adrienne Wendell quit running marathons seven years ago, for a couple of reasons. During her last race, her phone died and she didn’t know that her young son had been injured in a hit-and-run accident until she crossed the finish line. While he ended up being okay, her guilt at putting running before him made her give up her passion. She also spoke out about her former coach sexually assaulting her, right before he died, making her a target for internet trolls. It’s not until she gets a personal invitation to the “Hot & Sandy” race that she decides to run again.
Boones has hosted two of these ultramarathons, and this will be the third and biggest. It’s five days of running through the Sahara Desert, covering 250 miles of Morocco while carrying your own supplies and dealing with the harsh environment, all for the shot at $500,000. But Boones doesn’t make this seemingly impossible task any easier; he is known for adding “surprises” to his races, purposefully making tracks and rules that put people in danger, and overall being a sadistic jerk.
Adrienne flies to Morocco, joins up with some other runners she knew back in the day, then finds out her ex-husband Pete is also running. Furthermore, she finds out he’s engaged..to Boones’s daughter, Stella, who handles the photography for these marathons. The book is written from their points of view, along with excerpts from the Ultra Bros podcast, hosted by Jason and Mac. They knew this race will be monumental, not only because of what the contestants have to endure, but because Adrienne will be there, with all of her history dragging her down.
This book was flat-out AMAZING. The author also ran a marathon in the Sahara Desert, and you can tell from the imagery and the internal dialogue of the characters - so many times I felt like I was right there in the desert, too. There are so many layers to this book - it’s not just about the race, it’s about Adrienne’s love for her son, Stella’s hesitant love for her family, and the mystery of the dead coach. Did her son’s accident have anything to do with her outing him as a sexual abuser? If it did, can Adrienne forgive herself? Who will win the race, and will anyone die trying? This was unbelievably suspenseful, thrilling, unique, enthralling and heartbreaking. Five stars - don’t sleep on this one. It will probably end up in my top five books of the year!

There are so many layers to this book - it’s not just about the race, it’s about Adrienne’s love for her son, Stella’s hesitant love for her family, and the mystery of the dead coach. Did her son’s accident have anything to do with her outing him as a sexual abuser? If it did, can Adrienne forgive herself? Who will win the race, and will anyone die trying? This was unbelievably suspenseful, thrilling, unique, enthralling and heartbreaking. Five stars - don’t sleep on this one. It will probably end up in my top five books of the year!
(Thank you to Doubleday Books, Amy McCulloch and NetGalley for the ARC in exchange for my review. This book is slated to be released on July 1, 2025.)

4.75 stars rounded up (would have been a solid 5 stars but deducted 1/4 for who was the hit and run driver!). This one is very much in the vein of Breathless, which sees a group of people in an extreme environment, as people get injured or killed… who is behind it all? This one is the opposite extreme to Breathless, being set primarily in the Sahara desert (barring the opening in cold and wet Yorkshire, and flashbacks to sunny Ibiza), and whereas before I found the scenery/temperature descriptions monotonous in Breathless, I didn’t find that as much with Runner 13… maybe it’s because as a runner myself, I was more interested in the ultramarathon race they ran? (Though god knows I couldn’t do that race, furthest I’ve managed is 10K! If I ever worked up to ultra distance, it wouldn’t be in the extreme hot or cold).
Overall I liked the characters and plot, which ticks along at a good pace. You suspect several of the people, and happily I did spot a few things ahead of their reveal which is always nice! My only tiny niggle was in who was revealed as the hit and run driver, and the real truth never being told… hence 1/4 star deduction - but otherwise a solid excellent read and I’d recommend it! You might even want to lace up your running shoes after…

Bravo Amy McCulloch! Add me to your fan-base.
Runner 13 puts new meaning into the words: "RUNNER" and "THRILLER". Everything about this novel was interesting, competitive, enlightening, thrilling, and pretty dangerous. I read this both on e-book as well as on Audible Audiobook (which I purchased because it is my preferred method of reading). You'll meet sympathetic characters and spiteful, nasty characters as well.
The FMC is Adri and her family includes her kind/caring, ex-husband, Pete, and their young son. The running world seems to be a small one in this novel, especially when it comes to the elite ultra-marathon runners who are challenged with an exhausting and dangerous race through the Sahara. Yes, as in the desert. Wind storms, no cell-phones, limitations, and the runners have to carry everything they need. The man behind it is evil and awful, but it made for a good backdrop full of tension and drama. You'll meet other meaningful people who are involved in the personal lives of some of the runners, the photographer, and the -ex. One of the coolest things on the audiobook version is a feature where there are 2 men who run a live-action podcast during this marathon. The male podcast narrators share coverage of events in the form of a break from the 2 female narrators (who are both outstanding) and are on "live", which brings humor, information, interest, and a great element to his new novel, Runner 13.
Runner 13 happens to be the lucky # given in the race to Adri, a competitive, seasoned, marathon runner, and this is not her first rodeo in any form. There are many twists and turns and it's fun to be along the ride (or run) with Adri and her competition.
Thanks to NetGalley, the author McCulloch, and the publisher for this fun and fabulous e-book. NOTE: I purchased the audible audiobook because it's even better to have the voices and M.C.'s doing the sound bits. Get it now!
Publisher's Blurb: An exhilarating thriller set against a 250-mile foot race in the Sahara Desert, where more than one ultramarathoner will be running for their lives. Seven years ago, Adri left the running world after a major scandal. She leveled an explosive, and as it turns out career-ending, accusation at one of the world’s most celebrated coaches—and then he died suddenly. Now, after years away from the limelight, she’s ready to race again. Adri is hungry for a challenge, and she’s picked one of the toughest events a 250-mile trek through the Sahara Desert organized by a mysterious and famously sadistic race director.

Alright, fellow thriller fiends, gather 'round, because Amy McCulloch is about to drop a bomb of a book on July 1, 2025, and it's called RUNNER 13. If you're a fan of high-stakes, adrenaline-pumping reads that make you question your own sanity (in the best way possible), then STOP EVERYTHING and make sure this is on your radar.
Remember how "Breathless" had us gasping for air on a mountain? Well, this time, McCulloch is taking us to the Sahara Desert for a 250-mile ultra-marathon called the "Hot & Sandy." And let me tell you, "sandy" is probably the least of anyone's worries in this book.
Our protagonist, Adri, is an elite runner trying to stage a comeback after a past scandal. She's got bib #13, which, if you're into superstitions (and in a thriller, you should be!), already screams "DANGER!" The race is organized by the infamous and mysterious Boones, whose events are notoriously sadistic. So, you know, just a chill, relaxing jog through the desert. NOT.
Things quickly go from "extreme endurance challenge" to "OMG IS THAT A BODY?!" because, naturally, someone is turning this race into a hunting ground. Adri isn't just trying to win; she's trying to survive a killer stalking the hot, vast, unforgiving dunes. And being at the front of the pack, with that chilling number on her back, puts her squarely in the crosshairs.
This book was a ridiculously immersive experience. McCulloch's own ultra-running background means every blistering step, every moment of dehydration, every psychological battle felt terrifyingly real. You'll practically feel the sand in your teeth and the sun scorching your skin while you frantically flip pages.
If you fancy a story a la Agatha Christie meets Marathon des Sables with a dash of "who's going to die next?!" energy, then this is for you reader. If you love a good mystery blended with relentless suspense, where the environment itself is a character trying to kill you, then Runner 13 is going to be your summer must-read.

Ugh. This author. Not sure why everyone likes her work so much. The concept was incredibly intriguing, but the execution was just bad. She has all the hallmarks of an immature writer… melodramatic chapter cliffhangers, formal (unrealistic) dialogue, over-explaining, a Scooby-Doo ending. Blerrrrgh. I mean I’m clearly an outlier here, so take all this with a grain of salt… but hey, at least I finished her book this time. Progress?

[IN PROGRESS]
Adrienne (Adri) Wendell accepts an invitation to compete in the elite section of the "Hot and Sandy" ultramarathon, the latest gruelling race devised by an enigmatic American named Boones. Seven years previously, Adri became embroiled in a professionally devastating scandal, the nature of which isn't revealed until later in the book, closely followed by a near-miss in which her then-3-year-old son was apparently targeted by a rogue driver. It's Boones' promise to reveal the identity of the driver to her that persuades a reluctant Adri to take part in "Hot and Sandy" after a long break from the professional arena.
Meanwhile, Moroccan-American woman Stella Mahmoud, Boones' estranged daughter, is also associated with "Hot and Sandy", but in the capacity of a photojournalist following a group of runners who are participating for charitable causes. She harbours deep resentment towards Adri, having also been embroiled in the events of seven years ago that culminated in the suicide death of her younger sister, ultramarathon runner Yasmin.
Chapters from both Adri's and Stella's first-person perspectives are punctuated with transcripts from the "Ultra Bros Podcast", based in the UK and following the events of the race.
Elite runners and paying amateurs converge on Ouarzazate, Morocco, on the fringes of the Sahara Desert, in anticipation of the race.
"The challenges of the race I can handle - the heat, the miles, the pain. But what if someone is out there, wanting to hurt me? (p.106)Runner 13 is a gripping mystery-thriller, set against the backdrop of an ultramarathon taking place in the western Sahara desert in Morocco.

Really, really good audiobook, but meh story. This was really engaging and had some good twists, but overall I was unsatisfied with the conclusion. Also, I absolutely hated Stella. When she was first introduced I found her to be really annoying and she honestly just got worse as the book went on. In a lot of ways, she ruined the book for me.
I liked the author's other book (Breathless) and her other release sounds interesting, so I'll probably give that one a try when I'm in the mood for another thriller.

4.5 ⭐️ - tons of fun! I love the way Amy McCullough writes about sports that push humans to their limits. She makes you feel like you are right there alongside them and spares no details. Then throw in some killer twists and voila! A great time!
January 3, 2026
This was such a fun thriller to start the year with! Very unique setting at an ultramarathon in the desert and some great twists!
August 4, 2025
This was good. I’m not a huge thriller fan but this one held my interest and didn’t elicit any significant eye rolls, which means I stayed engaged, didn’t predict twists and enjoyed the ride. Being a runner myself (not one like these characters, though! Hoo boy!) I found the ultrarunner culture fascinating. But I could relate to the “pain cave” from a few races I’ve done, and I understand the determination and grit required to push the body beyond expected limits. Clearly the author does too - this was a voice of experience! Yes, there’s some belief suspension, but often that’s what makes a good story. Nice fast light read - recommend!
March 5, 2025
Amy McCulloch is absolutely fantastic at writing this sort of novel. Breathless had me completely immersed in the mountain-climbing world, and this one had me fascinated by ultra running. The research that went into writing this book was so evident, and I am in awe of anyone who genuinely runs such insane distances!
The world-building was brilliant, I really felt the oppressive heat and sheer scale of the Sahara desert, and could easily picture the setting for the race. The characters were extremely vivid too, and I really enjoyed getting to know them and following their story.
I would 100% recommend this book. I really enjoy a book where I feel that I have learned something as well as just liking the story, and that was definitely the case here.

Fast paced and a lot to unpack. I wasn’t 100% satisfied with all how everything wraps up BUT it was an incredibly unique setting and context for a story so I really enjoyed that.

And oof! This author is just an amazing human - she used her real life marathon run in the Sahara desert as inspiration for writing this book. (Minus all the dying.)
“And, in his mind, diamonds are only made under extreme pressure. Otherwise they remain part of the dirt,” (p. 104).
Adrienne has just received a special invitation to one of the most selective marathons in the world. At first, she thought it had to be a joke - until she turned the invite over. What she saw on the back? It stole the breath from her lungs. She’s going to this race - it wasn’t a joke.
The race? Only ten people have ever finished it - and none of them were women.
Boone, the sadistic mastermind behind the event, has created a brutal, nearly impossible course. He’s not just the head honcho - he’s a twisted genius with a plan that pushes runners to their breaking point. And somehow, 34 runners have already dropped out before the race even starts.
But with half a million dollars on the line, what would you do to win?
Then there’s Stella - she’s here to document the race as a photographer. She also happens to be the race owner’s daughter… something she doesn’t like to advertise. Oh, and did I mention? She’s now engaged to Adrienne’s ex-husband. Yep.
Adrienne is Runner 13. The runner expected to either win it all - or crash and burn. And she has the number.
Let the race begin.

Oof! The drama!! I devoured this book. It was an absolute blast to read. When I first discovered this gem of a book I knew I had to read it - and Amy DELIVERED. The setting? Perfect. The theme? Even better.
It entertains straight through to the jaw-dropping end.
🎧 I listened to the audiobook while following along, and let me just say - this is one of those stories you have to experience in audio! The narrators bring this to life. The podcast chapters were equally amazzzzing. Jill Winternitz and Sarah Durham deserve awards for this performance.

This book needs to be a movie or limited series. 🥳

Imagine running for your life across the scorching Sahara Desert, where every step could be your last, that's the exhilarating world Amy McCulloch has carved out in her unique thriller niche. "Runner 13" showcases her talent for combining extreme environments with endurance sports, creating the perfect backdrop for heart-stopping suspense.
The chase scenes left me breathless (no pun intended). I found myself reading with tense muscles, as if I too was racing across scorching sand dunes, heart pounding, desperate to escape whatever was closing in. McCulloch has a knack for making you feel the physical strain alongside the psychological terror.
Adri quickly became a character I rooted for wholeheartedly. Her guts and resilience shine throughout, but what really hooked me was understanding her deeply personal reasons for joining such a punishing race. By contrast, I struggled to connect with Stella. Her storyline never quite grabbed me the way Adri's did, and I found myself rushing through her sections to get back to the main action.
McCulloch's writing is impressively tight, with not a wasted word in sight. The reveals came at perfect intervals, each one genuinely surprising me when I thought I had it all figured out.
That ending, though? My moral compass went haywire. Days later, I'm still debating whether I loved or hated it. The best kind of ethical gray area that makes you question what you would do in the same situation.
The overall audiobook production was an immersive, pulse-racing listen that kept me riveted through every chapter. The dual narration made the POV shifts more distinct, especially when experiencing the book exclusively through audio.
Despite my mixed feelings about the conclusion, "Runner 13" is absolutely worth your time especially if you crave thrillers that venture beyond ordinary settings into territory as unforgiving as the human psyche.
Special thanks to Penguin Random House Audio for my gifted copy. As always, the thoughts shared here are completely my own.

I absolutely loved this book. I'm not a runner in any stretch of the imagination but my husband is. In fact, he used to be an ultramarathon runner so reading this felt like stepping inside his world and I could understand more about what his body would have gone through. Also recognized a few famous races thrown in!
I loved Adri and her resilience and determination. The storyline was easy to follow and oh my there were some shocks and twists too.
Felt like I was actually there! Hot & Sandy is not for me! Brilliantly executed and an all round fantastic adventure thriller. I'm now giving it to the husband to read.

I am a huge fan of Amy McCulloch. This book was about ultramarathon runners and ir was fast paced, gritty and completely unputdownable!!!
I love the sport angle in her books and I almost felt the pain that runners must feel when they reach that point of no return in their races! This was such a relatable book for me!!! Excellent!!!!

This is an incredible heart pounding story of survival. Boones has invited runners to compete in his race. Each runner is promised a special reward that can only be granted if they win. This race will not only test their endurance but will also put their lives at risk. If you love reading about corrupt and evil, revenge driven, along with strong characters then you will differently love this book.
Everything about this book was so interesting including the characters, the plot, and the setting. It was chilling knowing that there was someone targeting the runners but not knowing who or when they would attack next. Just when I thought I had figured out who everyone was and their involvement in the situations of the story, a shocking twist would be revealed that would make me second guess the characters intentions. I had predicted a part of Stella’s secret but when it was all revealed I was surprised by the true extent of her secret.
My favorite character was Adrienne. Her determination and grit for surviving and was what i loved most about her character. I was so worried for her throughout the book.

“Runner 13” by Amy McCulloch is a tense, and gripping thriller that will leave you breathless! The story revolves around a fiercely determined woman who was once a rising star in the world of ultramarathons. She gave it up years ago when her young son was hit by a car while she was racing and unable to come to his aid. At the same time she leveled a career ending accusation to the world’s most celebrated coach that ended her career in disgrace and mystery.
She became an instant pariah, but now after 7 years she has been invited to run the race of all races, 250 miles in the Sahara Desert. She participates in the race even though it organizer is know to be a sadistic and elusive. As the race begins the Sahara becomes a fantastic character itself, a living breathing threat and our heroines journey to peel back the layers of betrayal, trauma and ambition are riveting and explosive.
I was breathless reading the whole time and finished the book in one sitting. A unique story about reclaiming one’s power and the strength to survive. I loved it!

All I can say right now is WOW. Something about Amy’s writing that has you on the edge of your seat from start to finish!!
A fantastic thriller that grips you right from the start to finish with a twist bigger than the sandstorms of the Sahara.
Make sure you grab this book!

I have been wanting to get into reading thrillers in an attempt to branch out and this book felt at a great intersection between exploring a new genre and an interest of mine: running. Although, I do not participate in ultra marathons, I found Amy McCulloch's descriptions about running and the depth of feeling involved to resonate with me.
Adrienne, once an acclaimed distance runner, has taken years off from the sport after she felt a terrible accident involving her son was caused by her status in the community. After years go by, she is offered the answers she has been looking for, if only she finishes a race.
However, it seems those invited to race have more in common that any of them realize, as they all race for their own promised reasons the route turns deadly. It turns into more than a race to the finish, but a race for their lives.
While we are given multiple points-of-views, there are still so many things that the characters know that we don't. I have realized that, although the plot of the story feels fast and that there are so many page turning moments at the end of the chapters, I needed a lot of breaks. I think maybe, I'm not ready to but a full-on thriller girlie. I was so nervous!
I had a great time with these characters and I am looking forward to reading more from McCulloch in the future! There were some points where, even though we were in different POVs, the language felt a little too casual, but maybe it was just me feeling weird about reading the word "legit" during a descriptive paragraph.
The Characters felt well defined and clear in their voices and motives. The twist was wild but also believable and the dialogue felt natural.

While we are given multiple points-of-views, there are still so many things that the characters know that we don't. I have realized that, although the plot of the story feels fast and that there are so many page turning moments at the end of the chapters, I needed a lot of breaks. I think maybe, I'm not ready to but a full-on thriller girlie. I was so nervous!
I had a great time with these characters and I am looking forward to reading more from McCulloch in the future! There were some points where, even though we were in different POVs, the language felt a little too casual, but maybe it was just me feeling weird about reading the word "legit" during a descriptive paragraph.
The Characters felt well defined and clear in their voices and motives. The twist was wild but also believable and the dialogue felt natural.
