10+ miles, 110 minutes — cool weather moves in, and makes all the difference for a brisk mid-afternoon jog (from home via Georgetown Branch, MitP course, and Rock Creek trail) with 7 measured miles at an average 10:16 pace (+/- 13 seconds) ... three gasoline-engine-powered mega-leaf blowers under/near the Trestle offer the main hazard (airborne dust) ... alas, at mile 8 suddenly I hit, if not The Wall, at least The Curb (low blood sugar?) ... abrupt energy loss leads to much walking and ~13 min/mi on home stretch ... wildlife: one deer on the other side of Rock Creek ...
