Notes
Per the suggestions made on the coaching forum, I am trying Low HR training. Easiest 3 miles from an energy standpoint, hard to keep my HR in zone, especially at the end.Aimed for 65% to 75% of max, which was 124-144, ended up averaging on the high side of that scale.
TM was at 2% incline. Training for a HM will be agonizing at this pace, but I do feel like I could just get back on and do another 3 right now, if I had time.I guess I'll be getting aerobic training from my cross (swim/bike).
