This is a book by ultra runner Pam Reed, who won the Badwater Ultramarathon 2 years in a row, beating everyone, men runners as well. She is a pretty amazing runner, a kind of freak of nature--in that she runs and runs putting just enormous miles in and not getting injured and able to bounce back almost immediately. The book came out in '06 I believe so it is a little dated in that I am not sure what she has done since then. At the time of the book she was around 45 so her time as an elite runner was probably shortening.
The other really interesting thing about her was that she has battled anorexia from high school into her late 30s. She says it is still with her but she is controlling it. Kind of makes you wonder and she mentions this in the book, that her experience with anorexia may have helped condition her body to perform with little food like what happens in ultras to a degree. Obviously she says she would never wish anyone to have or go through anorexia.
I will be posting it on PBS at some point, there are only 3 WL for it at this time so probably won't wait too long before posting. I am still reading Life of Pi, but it has been ignored for a few days again. I have also started Enough by Juan Williams and still working slowly on Memory Eyes Breath. Not sure if I will look for another one, might wait a day or so to get some more read on these first.
