In a recent 45 min crit run at moderately hard pace (for a hacker like me - just starting in C grade vets), I got into a break of 2 in the last 5 mins and found that the highest my HR got in the final uphill sprint was about 7 bpm below max (and I've seen max in non-racing situations eg steep climbs). I would have thought if it was ever going to go to max (or even above), it would be when you were really giving it everything in a sprint.
So does going pretty hard for 45 mins (or longer) mean you are not going to get your HR right up at the end no matter how hard you push? Obviously speed & power will be down a bit compared to when you are fresh, but I would still have expected HR to go to max.
Just curious ....
