Run - Treadmill (Treadmill) 1:00:00 [4] 9.54 km (6:17 / km)
2:45pm - 5x 5min killer hills - 16%, 17%, 18%, 17%, 16% grades - brisk walk. Fast 5 minute downhill run between. Felt good - actually slow ran the last hill for a couple minutes at 4.5mph. Most were at 4.0 mph though.
Run - Treadmill (Treadmill) 1:00:00 [2] 12.34 km (4:52 / km)
6:45am - easy hour on the treadmill. Kept HR under 137 (75% HRmax) for 45 minutes, then did a brief bout of speed (5 minutes) then cooled down. Speed stuff pushed HR into the 170's briefly, but if I maintained form, it kind of sat in the low 160's - kind of surprising to me.
