Seven seconds separates two runs

Today's run (street): 2.5 miles

This morning's run was almost exactly like yesterdays. In fact, the only difference was that today's run took me seven seconds longer than on Tuesday. Same route, same weather conditions, same start time. I think my seven second difference happened in the first few minutes when I got off to a slightly slower start. My standard practice has been to start at a moderate pace and gradually increase my speed so that I attain negative splits on every mile. I try to throw in some anaerobic sprinting at the end of my last mile which, at the end, tells me a lot about my state of conditioning.

Although Sunday's 6+ mile run would have been a typical weekend distance for me a few months ago, it was a noticeable jump in length compared to my recent runs. I was glad not to have suffered any ill affects from going 30% longer than usual. No second day hamstring or calf aches like I'd get following a 10K race or a 10 mile recreational run. I'm thinking about upping my distance even further this weekend and targeting 8 miles of LSD. I think if I reestablish my long run base to the level I maintained in winter I'll do okay at the Dirty Sock 10K later this month.
