I received this book for Christmas and have started reading it early. I really enjoy the book and it gives some good pointers and has some enspiring quotes. Last night I went out for a short run. (Yay for being in the first week of my new training program). Anyways, during the two miles that I ran I thought back through the book and the tips on breathing and posture. I would say that it helped. I didn't realize that I tense my toes and hold my hands in a tight tight fist while running. By focusing on relaxing and breathing correctly, I was able to make it through the run without being sore or winded. I only walked 3 times during the first mile (for 3 - 0.05 blocks) and ran the next 1.03 miles back home. Score! I am exicted to read more of the book (I am only like 1/4 through it) and get more running tips.
