How do I accurately determine max HR? Do I do a run to warm up then sprint up a hill to exhaustion or do I do a set distance at gradually quicker pace until I'm flat out (on the floor)?
Answers and suggestions gratefully received.
I have a HRM and have recorded values (average and maximum HR) from a 5 mile and 10km race in the past 6 weeks. However, according to those values I am running at 92-95% MHR in my races! I somehow think my max HR is higher as it would then give me a figure which would make my av HR in a race about the 85% mark not the 95% mark!
