The end of the 2025 season was definitely the right time to read this book. From Jakob Ingebrigtsen's utterly dominant and record breaking indoor season (we're not gonna talk about his nonexistent outdoor season, but hey, he broke 2 world records in one race during the indoor season, who else does that?), to the podium sweep by 3 Norwegians in the Ironman World Championship (2 of them heavily featured in this book, and the other one is their training partner), and not to mention the fact that a Norwegian also won the women's world championship.
In other words, if you're a fan of endurance sports (especially distance running and triathlon), it's hard not to notice the fact that Norway has been punching above its weight these past few years. And this book gets to the possible reasons as to why that's been the case. One of those things being the threshold training that's been very popular recently.
Honestly I only read this book for the threshold stuff, because as someone who likes endurance training but hates training hard, threshold training has always been very appealing as you don't have to try as hard compared to if you're training using a more conventional training method, or so I thought, but of course it's all more complicated than that. And that can be said about this book in general.
Not only will you get a pretty clear explanation of what threshold training is according to several people who are pivotal in popularizing the whole thing, but this book also contains a short history of the Vikings, life in Norway, and most importantly, other parts of the Norwegian method that are maybe not as popular as the double threshold craze that's been taking over social media.
It's a well written book, very easy to understand even to someone who doesn't know much about exercise physiology. And it feels like a thoroughly-structured book, encompassing many important figures in the history of the Norwegian method, and it shows how it's not just all about the Ingebrigtsen family, although they're perhaps the ones who popularized it the most.
Even though the specifics differ depending on who you're talking to, the book makes it clear that keeping intensity under control during hard sessions in order to enable quicker recovery and maintain high training volume is the key tenet of the Norwegian method.
Could the book have gotten more in depth about the method itself? Maybe, but that would probably sacrifice the readability of the book in favor of science that most people won't understand, and the book points to places where readers can find stuff like that, like Marius Bakken's website.
So, overall, while it might not be as in depth as some readers want, this book is still an excellent overview of the people involved in the Norwegian method and the long history behind it.
