I've never known my threshold HR. I averaged 190 over my last 20 min FTP test so it's a bit odd I could do the same for over an hour. Maybe it being race day and adrenaline etc may have something to do with it. Or maybe my HRM is broken. Or maybe I am dying.
It does seem high, especially for cycling. I would expect that for the run leg. What threshold HR would you usually expect?
I find my race day HR always a bit higher than when training hard. Plus it was a fairly hot cycle yesterday. Too many factors to be sure
My cycle average HR yesterday was 153! Maxed at 174.
