From parents to one-mile loop, 4 loops, and back. 8.7 miles, 1:20:38/142 (9:16 min/mi)
Very good pace at the heart rate for me. I've let myself hover around 145 instead of staying strictly below it. The four one-mile loops were 9:09/140, 9:12/143, 9:12/143, 9:10/145.
I seem to have naturally fallen into the higher cadence now. It looks a bit ridiculous though. Counting right arm swings, I'd get 44 or 45 per 300 seconds which is 170-175 steps per minute.
