Aim for 1 Mile

On average, it takes one mile of walking or running to burn 100 calories, says nutritional biochemist and exercise physiologist Shawn M. Talbott, Ph.D. “So the faster you can cover the mile, the faster you can burn off the 100 calories.” A treadmill calculates your distance as your walk or run, while four laps on a running track will constitute a mile. You can also use Google’s pedometer map to plan a mile course around your house or office, or use a traditional pedometer: 2,000 steps equals about one mile.
