I agree wholeheartedly with your comments about the free running book.
It is AND entertaining, AND very useful as well.
I have been following the method described by Hadd in the e-book and over the past 20 weeks I have been dropping times significantly in the tests he sets out to do.
I have got some races coming up in the fall, and I have never been so convinced as now that I am going to break some personal records!
Keep those running tips coming, Dominique, I love them!
