Time to calculate. Treadmill speed is distance / time. Divide the distance (belt length x number of revolutions) by the time measured. For example, if the belt length was 3 meters, and it took 20 seconds for it to do 15 revolutions, then the speed is (3 x 15) / 20 = 2.25 meters/second (or 8.1 km/hr or 5 mph). If the treadmill is off you’ll …
· But can these machines be trusted? Last month a study was done to see just how accurate these machines are. The results are a little mixed. First off, is a mile on a treadmill really a full mile? Thankfully we can say yes, as long as the treadmill is properly maintained. A mile on a treadmill vs. a mile outdoors is going to feel different though.
Treadmills provide a measurement of the distance covered in a workout, typically in either kilometers or miles. If your treadmill isn’t displaying properly, modify the display to show the correct measurement. However, be aware that the distance measured may not correlate exactly to the distance you’ve actually run or walked.
· Distance is a respectable, but not exact, measurement, regardless of how your treadmill shows it. On a treadmill, you run differently than on a track, engaging your knees differently and powering through the run slightly differently. Each kilometer you run on a treadmill is usually about 40 meters short, corresponding to about 120 feet every mile.
I absolutely love my treadmill but I do agree, 4 miles an hour on the treadmill seems much faster than 4 miles an hour outside. I have a brand new gym quality treadmill so I’m pretty sure it’s accurate. 0. Montarosa456 Posts: 133.
· Then you update the distance on the watch to match the distance shown on the treadmill screen. It will save this data and try over time to make your treadmill runs more accurate. At minimum you’re able to update the distance, which means you’ll have the correct data in your files for how far you ran and the total time.
Distance is typically figured on a treadmill by simple multiplication (time multiplied by speed). However, effort on a treadmill with no incline is not an “accurate” measurement of how you would perform running outside.
· 05-04-2017 10:51. @Sejpal55, the distance recorded on the treadmill is more accurate because it uses the revolution of the belt to measure distance, while the Fitbit uses the number of counted steps multiplied by your profile stride length to calculate distance. The actual stride length on a treadmill is never the same as it is outdoors.
When running or walking with GPS turned off, speed, distance, and cadence are calculated using the accelerometer in the device. The accelerometer is self-calibrating. The accuracy of the speed, distance, and cadence data improves after a few outdoor runs or walks using GPS. TIP: Holding the handrails of the treadmill reduces accuracy.
· Apple Watch uses different sensors and data sources to track the results of workouts, depending on the activity type and their availability. For example, with Apple Watch (first generation) and Series 1 models, the watch can access GPS data from the paired iPhone if it is taken along during outdoor walking, running and cycling workouts.
