Questiong about HR Max and zones
Hi, I've been running since April 2026, three times a week (tempo, Z2, and a long run), and I still don't know my exact max HR...
Currently, I'm just using 200 as my maximum. However, in races, my average heart rate is around 185 and maxes out at 196. I highly doubt I could sustain Zone 5 intensity for that long, so my actual max HR is probably higher.
I use Polar H10+ for measuring.
Half marathon - avg: 185, max: 196, time: 1:59:13. The run became increasingly difficult from around the 8km mark. The final kilometer required all my remaining strength to finish the challenge under 2 hours.
