So my max heart rate is 197. And I averaged 190 over a 25 mile course (London tri on sat) for 1hr08. Does that mean my threshold HR is 190? Seems too close to max to make sense?
Course was different on the Saturday and Sunday. I was on sat and it was 4 laps between just shy of blackwall and University of East London. Sunday was longer but only two laps I believe
