Question: how many calories do you burn in a 2 hour bike ride?
Answer: The faster you make your bike go, the more calories you burn. A light ride of 10 to 11.9 mph burns 844 calories for a 155-pound person. Go at a vigorous 14- to 15.9-mph pace and burn 1,408 calories. When you are racing at paces of 16 to 19 mph, expect to sizzle 1,688 calories in two hours.
