Temp 50, DP 48. Ran around DC (Dupont to U to 17th to Dupont to Cap Crescent) and then hit the Cap Crescent and did 4x800, split as 3:03, 3:06 (traffic),2:58, 2:55. Right foot held up quite well, but left piriformis tight, making left foot cramp like crazy. Also felt like I just couldn't run fast in the pure flows - there's just no reboundfrom them.
Really nice weather though - great to be out there.
One puff of DUlera in the morning. Just did light injury prevention work at gym.
