Pedometers with the measurement of the distance traveled

Distance traveled

— distance traveled can be calculated using either step count data or the built-in GPS module. Although both methods have their drawbacks, following usage guidelines typically results in negligible measurement errors. Notably, pedometer data is effective on a treadmill, whereas GPS is ineffective in such scenarios since, from the satellite system's perspective, the athlete remains stationary. Many treadmills feature their own distance measurement tools.
