As you see above the number of calories burned biking a mile will depend on your weight and how fast you cover that mile, but as a general indicator hereâs a couple of examples: 1  a 150 person cycling a steady pace of 14 mph will burn 48 calories per mile, that same person traveling at 20 mph would burn 56 calories per mile. A 200 lb person biking at a normal speed of 14mph will burn 64 calories per mile, if they sped up to 20 mph this would increase to 75 calories per mile.
