I ran two laps today. I felt pressure in my feet, which was a little disconcerting, but no actual pain, so I continued. It's been a couple hours and I still don't feel any pain, so I think I'm good. I'm hoping that the pressure is the foot's equivalent of positive muscle soreness. Either way, I was afraid to run any longer. I didn't feel that pressure last time. We'll see how my feet feel on friday. I may or may not run a full three laps.
