To compare the calories burned running and cycling, there are some conversion factors you can use to get a rough estimate. If you cycle at 15 MPH for 10 miles, that's like running for 10/3.5 or 32.7 9 miles. Just look up your cycling speed below and divide the number of miles by the conversion factor to get the running miles. This conversion assumes you're on a road bike, on the flat, not drafting, as well as making many other assumptions, so use this as a rough guide only.
