10 easy + 10 @ MP, 1 CD on the levee. Warm and humid. It was 75F w/ 71F dew point by the finish. Can't say how frustrated I am that it's this humid in February. I did the first 10 as an out and back and stopped at the house to switch to flats. I tried taking some honey and water at that point as well.
5:36, 5:36, 5:38, 5:48 (big dip & headwind), 5:39 (turnaround), 5:29, 5:31 (big dip & tailwind), 5:38, 5:44, 5:41
Avg = 5:38
The 2 5:30 miles surprised me since I didn't feel like I'd sped up. I was hoping to finish a little stronger, but I think the humidity got to me. There was some headwind on the last 3, maybe 5-10 mph, and those last 3 miles were pretty tough.
