It's just personal pressure on myself. That isn't entirely true. The Tuesday run I do is a group run, and there are some fast people. It pushes me to run faster.
I got back into running by making it a habit. It isn't a question of if I feel like running, it's a question of "is it Monday, Tuesday, Thursday or Saturday?" I'm enjoying the routine. I do an internal run, a fast run, a medium length run, and a long run. The mix seems good.
I never came close to maxing any part of the APFT. I never kept up my fitness when I was in the National Guard, and I'd barely pass each time. I'm sure I'd do better now (on the run at least) than I would then. I'm sure I ran a 14:15 in there, but at age 37 now I'd have a better score.
