Notes
Temp 26, DP 22. Met group at Carderock and ran out and back. Picked it up some on the tail end (starting halfway between MM 15 and 14) for about 3 miles, then pulled plug since my left leg was weakening on me and I couldn't keep my form together any more. Ended up with about 3 miles at ~7:00 pace.
Left leg fine for most of the run, though it did get tired at the end. I did have to focus on using it correctly, and the left foot did start cramping a lot at one point.
