Run - Road 20:20 [4] 4.7 km (4:20 / km)
ahr:138 max:178 rhr:49 slept:7.0
Tight calves (leftovers from A meet). No school so took the day off. Get a short early AM run in (about 6:30am, 30F overcast) before kids wake up.
Hard to get HR above 145, 178 was a brief spike about 4 minutes in. I usually seem to get a brief spike in HR between 3 & 5 minutes, then usually don't see it unless really pushing. Get it with or without warmup jog.
