Calculate how far you run by timing your workout and comparing it to the pace you set. A treadmill's speed settings typically range in pace from six- to 12-minute miles. Divide the number of minutes that you ran by the per-mile speed to calculate the total distance that you ran. For instance, if you use the treadmill for 60 minutes at a rate of 12 minutes per mile, divide 60 by 12 for a distance of 5 miles. Wear an external tracking device while running on the treadmill to automatically monitor distance if your treadmill is older or doesn't provide accurate speed or distance information.
6. Divide the distance the runner traveled by the number of seconds elapsed. Using the example length of 100 m (328 ft), if the runner took 10 seconds to run that distance, the runner's speed would be 100 m (328 ft) divided by 10, or 10 m/sec (32.8 feet per second).
