I went out for a simple 7 mile tempo run. 3.5 miles out at 8:30s and then trying for 7:30s back. At two miles back, I had to take a break. I made it back, but here are my splits:
8:25 (pace 1/2 mile)
7:38 (pace 1/2 mile)
The average pace was 8:00 per mile -- which is what I was targeting. But it was tough getting that last 1.5 miles in. The muscles simply didn't have the strength.
1.5 weeks for my leg to repair for the marathon.
