Have you also checked your heart rate whilst running to see if it actually is getting that high. I'm sure an Apple Watch is pretty reliable, but best to check properly.Delighted to stumble across this thread! Took up running during lockdown and I'm hooked. Out of interest, I'm wondering if some of you could help or give me advice. I'm 29, 5ft 2 and 128 pounds. Wear an Apple Watch and resting heart rate is around 64 bpm. Have been analysing my most recent runs and max HR hits 185+. I seem to be spending a lot of my runs in HR zones 4 and 5. Not sure if this is something to be concerned about? A friend told me that I shouldn't really be running in HR zones 4 and 5.
I think 185 does seem quite high though. For your age it should be 191, but not sure how accurate that calculation is (220-age). @nbx512 do you know if its a real thing? Or a random thing someone made up in the 60s like the 10000 steps
