Thought you might find this of interest.

A clubmate attempted to break the world hour record in his age category on the weekend.

Here is the shot of his power file. While he didn't set out to pace by heart rate - in effect that's kinda what happened. His HR went to "threshold" (whatever that is for HR) and he plateued there until near the end when failure came and he blew spectacularly.

See what happens to power (and speed) - a long slow decline while HR remained constant.

A great corollary example of "cardiact drift" - the "power decline at constant HR".
