A good view of a clear sky can also help a little.Ī better approach would be to run a known distance, either on a track or using a known course and calibrate against that known value. That will be a run that is reasonably straight, as twists and turns tend to reduce the GPS accuracy. The best run to use for calibration is a run that has the most accurate GPS data. That is because the Garmin recorded data is based on the Footpod, so it's calibrating the Footpod against itself. If you do not have a GPS signal, such as a treadmill run, then there is no calibration possible and this utility will show that no calibration can be automatically performed. The biggest flaw in the approach is that it relies on the GPS signal, and GPS is not that accurate itself. The advantage of this utility is that you can use any run to check the calibration and you can run much further. The calibration run is comparing the GPS distance covered with the Footpod reported speed. This is using the same principle as the Garmin calibration run, where you tell the Garmin to calibrate and then run about 1 Kilometer. That should be the same as the foodpod speed if the GPS is accurate and Footpod is calibrated.Ģ.1 Is this different to a Garmin calibration run? By looking at each position that is recorded, you can work out how far you've traveled and how long it took. If the Footpod is active, then the speed according to the Footpod is also recorded. The Garmin devices record your position along with other data such as Heart Rate every few seconds. TCX Exports from Garmin Connectcontain what looks like speed data from the Footpod, but it matches the GPS signal perfectly.
