I rode 25 min in the trainer to loosen my legs and then went out for a 8.25 mile run this morning. I tried loosing my shoe laces to see if that was contributing to my recent foot pain. That seemed to help... I believe my feet to be swelling over the course of the run and that the pain starts when the shoe tightens.
On a side note, I believe my IM run pace has slowed by 15-20 sec per mile with all this long slow training I have had to do. It has not been easy watching my speed slow and power dimenish in order to train for this race.
