The problem I see with this is the fact that heart rate does not respond immediately to increased work, and takes a while to come back down after the workload is decreased.

To the OP, calorie meters on cheap bike computers are based solely on speed and do not take into account basal metabolic rate, wind speeds, terrain, rider mass, etc. You might be able to make some sort of general comparison between two runs, but to do a really accurate test of this kind I think you'll need to start with a power meter.

At the ends of long rides, I find myself naturally trying to coast more. But I can't say if this is physiological or just psychological.
