Well this was suppose to be an easy 6 mile run according to the Hal Higdon 1/2 Marathon training. My wife got me a Garmin 305 for Christmas and I love it. It gives the opportunity to be the gear nerd that I am and post figures and nice graphs. I thought I was going out like I always did on my long runs. After mile 1 my heart rate was a lot higher then I wanted. I am not sure if heart rate monitor is messed up or what, but this seemed really high for the whole 6 mile run. I did run the course faster then I ever had, I was shooting for like a 9:20 pace/mile, and ended up doing a 9:10. I did not feel tired or felt that I was pushing myself. I guess the heart monitor hates OHB!!
