Notes
Treadmill again. First mile at 10:00, second at 9:31. Second mile didn't feel much harder than the first, to be honest. must just be the treadmill.
HR monitor said it was somewhere up in the 160s as I was running, if i recall correctly. Not sure what HR I'm supposed to be hitting on my "easy" or "long" runs.
Feeling more confident on the treadmill, not so concerned I'll run off the sides anymore!
