My hamstring is niggling. I can see the potential for this to bother me for months if I try to run much on it. I'll extend my rest week and I think I'm going to take the next 2 days off completely from running. Looking back after Chicago I want to see that I did the right thing today. It takes ~5 days off to lose fitness so I'm not worried at all about that. I was commenting to a friend the other day that the only reason I didn't place top 5 at Ironman Hawaii was that I never rested. If I only had the self control and confidence to do this in 2004...?
