Calories burt on an 8 mile back road bike ride?

Question

if i ride a four mile bike ride to a point, take a 10 min break and then ride another 4mile bike ride back to my house. this is all on dirt roads and up and down hills. how many calories would i burn?

Answer 1

I will take an off the top of my head guess and say 350-450 calories?  I think speed and intensity will make this vary.

Answer 2

Depends on how much you weigh and how big the hill and how fast you went.

Answer 3

Go to bicycling.com and click on the training tab. There is a calorie calculator there. Its results are usually very close to the numbers reported by heart rate monitors that display calories burned.
