I was in a 12 hr race recently with a 32 mile loop. My average heart rate
on the 1st lap was 150, 2nd lap 143, 3rd lap 139, 4th lap 133, 5th lap 129,
and 6th lap 128.
My perceived exertion was the same for each lap.
My speed dropped slightly for the first 3 laps but the 4th, 5th, and 6th
laps were the same speed.
Why was my average heart rate reacting this way?
