I depends on how fast you run and miles per hour u are running..
I have know people to burn about 1 to 3 thousand calores per hour running marathons. They all depend on the individual and their metabolism and other factors. Typically that is the range.
The number of calories burned per hour when running will depend on how fast you are running, your current weight and even such things as the terrain. You are going to burn a minimum of 472 calories and hour and could burn as much as 1675 calories (and possibly more). A couple of good charts can be found at http://www.nutristrategy.com/activitylist3.htm and http://www.mayoclinic.com/health/exercise/SM00109.
How many calories you burn by running 2 miles on a treadmill depends on many factors. How much you weigh and how fast you are running being the two main ones. On average, you will burn about 200 calories.
