Temp 36, DP 23. Ran out with Jamey, Nora, Marvin, and David, + Jillian for first few miles, towards Pierce Mill. Ran easy until mile 6, then turned and headed to zoo bathroom. After that stop, I picked it up on the way back to Fletchers. Split as first 6 at 8:55; next 3 at 7:27; last 3 at 6:44 (last mile at 6:38). Used albuterol inhaler 3 puffs in bathroom - breathing was good after.
