The weather cooled down and that made a big difference in my energy level during my run Tuesday. I decided as soon as I took off that I wanted the run to be fairly fast. For the sake of conditioning I feel I need to push it a little bit once in a while, and it had been a while since I'd done it last.
Inexplicably, I picked a rather hilly route for this effort. Even so, I started out with a 9:37, then did 9:05, 8:38, 8:42 and 8:36. I then did .68 mile at an 8:23 pace. The overall pace, then, was 8:52.
At this point, I was over a mile from home, and I really wanted the run to go 8 miles, so after a short walk I ran another 2.32, averaging 9:24. So I got a tempo run and an easy run in on the same night. Felt good all the way.

Then Wednesday night, with the rains coming down, I decided to get my run in at the gym. On the treadmill. This was kind of risky considering my recent injury problems associated with the device, but I felt confident nothing bad would happen.
Despite having already run 15 miles the two previous days, my legs felt surprisingly lively on the belt. I started at a 10 min. pace and bumped it up a notch every half mile until I was running at an 8:57 pace. After that I backed off a couple notches and finished at a 9:15 pace. I did 5 miles in 47:19, for an overall pace of 9:28.
