Normalized Grade Pace and Treadmill Equivalency Chart

Because of lack of wind resistance while running on a treadmill, the effort of running on a treadmill at 0% incline is less than that of running on a level road at the same pace. Below is a chart that you can use to get approximate equivalent efforts between running on a treadmill at different paces and inclines and running outdoors on a level surface.
