Here is a calculator, you can calculate calories you are spending in running. But please remember, each persons body is unique. No calculator can calculate the calories precisely. But it will give you a value which is close enough to the actual values.
I would like to remind you that if after running you don't eat too much, then body will break more fat at a later period when you are not running or doing any form exercise.
