In place of a long run on yesterday's training schedule, the assignment was to do 4x800s at race pace. So, I used my projected half marathon race pace per mile based on my current Magic Mile average, which is 21:02, which translates into a 10:31 minute half mile, 800, or "Yasso." I decided that, since I only had four of them to do on yesterday's schedule, I'd try to pick up the pace. After a walking warm up, I nailed all four of them, with some walking in between. I walked a half mile afterward to cool down.
Here are my 800/half mile/Yasso splits:
1) 0.50 in 9:51 min
2) 0.50 in 9:42 min
3) 0.50 in 9:47 min
4) 0.50 in 9:43 min
Not quite the negative splits I was going for, but not bad. I felt pretty decent afterward too, so either I didn't run hard enough, or I'm getting in better shape. A little of both, perhaps.
