beetle, I've read it, and I like it. There seem to be lots of tri books for women, and I bought this one and the one by Sally Edwards. IMO it's better than Triathlons for Women by Sally Edwards.
It has lots of good info and tips if you're starting out in the sport, with training programs, nutritional advice, and how to avoid injuries (and even training while pregnant). I still re-read it every now and then for reminders on what I need to be doing to get it right (like in the off season when I get lazy and need to get fired up again ).
If you can, try to go to a bookstore and read through it before buying. Then again, that advice is really for me, as I usually wind up flipping through a book, then get it home and realize that I don't find as helpful as I did when I was in the store.
Like I said, it's just my opinion, but I like the book!
