The funny thing about 50 Marathons in 50 Days was that I didn't expect it to be a book. The subtitle says something about how it will give the reader “the secrets to super endurance.” Opening the first page, there’s a lot of guff about how Dean Karnazes may well be the fittest man on the planet, as a bunch of Americans and American magazines have described him, but that he’s really an ordinary guy, “an extremely ordinary guy.” Get it? “Extreme.” Like, yeah. So. If he’s like extreme then that like must mean he’s amazing, right? End result: I expected a manual written by an American with a big ego and a naff-writing style.
