I have been listening to a lot of inspirational endurance athlete type books while training for a marathon, and honestly this is not one of the best. There is a fascinating intro about the history of the Ironman, but then it drags into a very long and boring stretch (the vast majority of the book) of basically just doing through the training logs of the participants, and reading their blogs (which in turn are just descriptions of their training). Too many characters that are not distinct enough so in audiobook form it is easy to zone out as to whose cold swim or century bike ride you are hearing about. Lots of stories of minor injuries and getting over them which don't really go anywhere. I will say that it does impress upon you the sheer volume of training that an Ironman requires, which blows my marathon training out of the water.
For this type of book I would greatly recommend Born to Run, Eat and Run or Finding Ultra before this book.
