text: my frind runs for 15 mints a day, i walk (not regular a bit fast ) for 1 hour, who is burning more calories?   it depends on the speed and what you both weigh.  assuming that you both weigh 150 pounds: running - 6 mph   170 calories in 15 min walking - 4 mph   340 calories in 1 hr  so if those weights and speeds were correct for you and your friend, you are burning more calories.  you can use the link in the source to test out different numbers.
