Speeds are calculated precisely to two decimal places. Most treadmills adjust in 0.1 increments, so round up or down based on your training preference.
Built for track athletes, road runners, and coaches who train on the track, road, and treadmill. Use it to replicate track workouts on a treadmill, match a target race pace, or set precise interval speeds for athletes.
Whether you're training through winter, recovering from an injury, or just prefer the controlled environment of a gym, the treadmill is a practical alternative. This tool makes the translation exact.
Select a distance, enter your split time, and instantly calculate the exact treadmill speed in both mph and km/h, plus equivalent times for common race distances at that pace.
Supported distances include 100m, 200m, 400m, 800m, 1600m, mile, 5K, 10K, half marathon, marathon, or any custom distance. The calculator accurately handles the distinction between 1600m and a true mile.
Time can be entered as seconds (e.g. 90 or 90.5), mm:ss (e.g. 1:30 or 1:29.5), or hh:mm:ss (e.g. 2:30:00).
Export, print, or bookmark. The 400m pace treadmill speed chart and mile pace treadmill speed chart let you reference your treadmill speed mid-workout without stopping to calculate.
See the distance conversion page to find out how far 100m, 200m, 400m, 800m, and 1600m are on a treadmill in miles and kilometers.
