Stiff

I ran 7 miles yesterday from the store with the running group. I felt ok for the most part, but I also felt really stiff. I went out in around 7 minute pace and came back probably around 6:30 pace. The run was uneventful outside of hearing footsteps from behind about 3 miles in. I of course didnt look back and proceeded to run the next half in 3 minutes. I later found out that it was a guy from the group who started out slower and was trying to catch up to me, not just some random runner on the trail.
