I donated blood on Sunday 4/14 (double red) and did a run workout today. I thought it’d be interesting to compare today’s workout with a similar workout I did in March:
Lap # / Normalized Power / Avg. HR / Efficiency Factor
3/12/24 - 6x 2:30 @ Z4
Avg. Temp = 59 F
Max HR = 171bpm
1 / 333w / 155bpm / 2.15
2 / 342w / 158bpm / 2.16
3 / 336w / 159bpm / 2.11
4 / 331w / 156bpm / 2.12
5 / 332w / 157bpm / 2.11
6 / 342w / 160bpm / 2.14
4/16/24 - 4x 2:30 @ Z4
Avg. Temp = 76 F
Max HR = 186bpm
1 / 337w / 176bpm / 1.91
2 / 325w / 175bpm / 1.87
3 / 338w / 176bpm / 1.92
4 / 334w / 177bpm / 1.89
My overall max HR is around 190. Training Peaks told me I held 184bpm for an entire minute today.
