Trail Running 50:00 [3] 5.2 mi (9:37 / mi)
shoes: Adrenaline 17 Gray
Greenbelt Park Perimeter Trail at noon. Intermittent sun, 60s, very pleasant. The time flew by.
First butterflies of the year. 2 polygonias of some type, one on the trail in a sunny spot, and one near the edge of the woods outside my building. These overwinter as adults, and fly out on a sunny day, sometimes even in winter.
