Is it higher though? I thought that it’s very pace dependent. So for instance, if you’re a strong cyclist but weak runner you could burn more per hour cycling. The same would be true in reverse.
For me a comfortable running pace is about 8:30/mile, based on my body weight of 135 lbs and the online calculators that works out to about 721 calories per hour.
For an hour of cycling, 230-240 watts is about what I can sustain comfortably, I believe that works out to about 850 calories per hour.
Likewise, I pushed for a mile as hard as I could the other day and hit 6:27. That works out to about 102 calories.
My all time PR for power at 6:27 is 315 watts which would work out to about 123 calories over that same time frame.
I’m guessing if I could get myself to run faster these numbers could flip?
