==How does it work?==
The Garmin devices record your position along with other data such as heart rate [[Heart Rate]] every few seconds. If the [[Footpod]] is active, then the speed according to the [[Footpod]] is also recorded. By looking at each position that is recorded, you can work out how far you've traveled and how long it took. That should be the same as the foodpod speed if the GPS is accurate and [[Footpod]] is calibrated.
===Is this different to a Garmin calibration run?===
==Frequently Asked Questions==
* Why do I see footpod [[Footpod]] data when I'm not wearing the footpod[[Footpod]]? ** The Garmin will record footpod [[Footpod]] data if you have the watch set so that the footpod [[Footpod]] is active, even if you're not wearing the footpod [[Footpod]] at the time. This is a bit odd, but there's no way of detecting if the footpod [[Footpod]] data is real or fake, though the calibration value is normally very close (within a fraction of a percent), with just rounding error discrepancies.
* Why is the 'actual distance' different from what I ran?
** The 'actual distance' field is updated based on 'good data', and ignores data where the footpod [[Footpod]] and the GPS are wildly different.
==Installation==
* Download the GUI executable from http://fellrnr.com//Utilities/CalibrateFootPod/GarminFootpodCalibration.exe
** You can also download the command line executable from http://fellrnr.com//Utilities/CalibrateFootPod/GarminFootpodCalibrationCLI.exe
* Check the executable for viruses (trust no one[[Trust No One]]!)
There is no further installation ;}
== Gathering the data==
This utility does not require a special calibration run to gather data. Any run with your Garmin 310XT and Foot Pod enabled will provide the data needed. Running at a steady pace will provide good data. If you take walking breaks[[Walking Breaks]], this will tend to produce a lot of variability.
==GUI Version==
* You can load a file that has been exported from [[Garmin Training Center]] (see below) using the File, Open menu.
* The graphs give a visual representation of the calibration data.
** The top graph is the distance recorded by GPS and the [[Footpod]]. The values vary, as the Garmin does not record at even intervals,
** The bottom graph is the scaling factor. The horizontal lines show the average and the standard deviations.
