As far as Calorie output, from what the apps show, my calorie output for running is almost 4 times as much for running, per mile distance. Haven't done the math as to what that equates to per hour.
These are just an example of the numbers you are asking about. The distances are shorter but you can get an idea.
Tuesday morning I ran 6.07 miles in 50:18. That is an 8:17 minute pace. I was not running hard or easy (my half marathon pace is 7:30 for comparison). It says I burned 640 Calories. I was wearing a HRM (Avg HR 145 BPM) so it is pretty close to accurate I guess. Temperature was 77, 100% Humidity (Houston), 0 wind.
Wednesday afternoon I went for a ride. Just an easy spin. Did 30.27 miles in 1:51:01. That is an average speed of 16.4 MPH. I burned 1,261 Calories. Avg HR was 137 BPM. The temperature was 90, 63% humidity, and 3 mph wind (although I think it was closer to at least 10).
So if you multiply the run by 4.33 to get to 26.2 that is 2771 calories.
If you multiply the ride by 3.33 to get to 100 miles that is almost 4200 calories.
None of this means anything really. Running is harder. Especially the longer you go.
