Not a running book I'd recommend. Overly simplistic, seemingly written for a future marathoner who's never spoken to another long-distance runner, never listened to a running podcast, never checked out a runner's blog, etc. etc. Some of the advice seems outdated or bad, like "eating one or two gels during a marathon should be sufficient" (to finish? Sure, probably. To finish at one's best pace, feeling as well as one can, doing as little damage to one's muscles as possible? Not sure any licensed sports dietician worth their salt would recommend the same).
I was hoping to pick up a tip or two, but wish I'd just checked out the training programs in the back and given this one back to the library. I found it interesting that you work up from four active days to five then back to four and three in the taper; I like a mix of conversational pace, tolerable discomfort pace, hills, and fartlek. Now after reading, I'm doubting whether it's smart to follow a training program located in a book with all sorts of other advice I found dubious. (Also the training calendar, described as a "visual guide to the training programs" at week 13 suggests "'back to back' long runs such as 10 miles on day 1, then 10 miles the next" while the written program has one long run of 20-22 miles. Well, which is better? Who should follow which recommendation? This book is not there to tell you. Disappointing.)
