Tony Lozano’s Reviews > Undead Ultra > Status Update

Quick read. A mom and her best friend who are ultramarathoners have to run 200+ miles to reach their kids during a zombie apocalypse. Flashbacks and interesting character development keep it from becoming a "run to next town kill zombies" exercise. I'm not sure how accurate the ultramarathon aspects are but they seem plausible and interesting. Drags for a couple of chapters in the middle but not excessively.
