Notes
Summary: Intervals: Run 3:15, Walk 0:45 (1st time for this).
This went well until the last 0.8 mile. This morning's humidity was beastly; it sapped me so that my legs felt like jelly, and I felt it wise to stop and walk home from the park.
Pulse/resp at finish: 150/23.
Route: SW 3.75 but stopped in park on the return.
Weather: Mostly sunny, 81°, dew point 75°, light south wind.
