I love my running book CHI running by Danny Dreyer, it really helps stop worrying about getting faster and worrying more about getting better. I have now been running for a year and a half, and have got my 10k from 66 minutes down to 60 minutes, 6 minutes over 18 months of training methodically, disciplined and hard....I keep hoping I will wake up one day and BE a runner. Although I do like it now.
(sorry about the student incident, I teach university freshman who average 16-17 years old and they CAN BE the worst). This makes triathlon all the more great
