Easy 1:00:00 [3] 7.0 mi (8:34 / mi)
TM - covered pace setting with towel. Ran for 15 min until it felt easy/medium - HR was at 124, strides were 150 per minute. Left if there for the remainder of the hour. It turns out I was at 8:20 pace. This felt a little hard, but HR for the last half hour only got up to 134 BPM.
