Revision as of 16:49, 3 December 2010

This is a small Windows utility that analyzes a run and calculates the appropriate recalibration for your Garmin Foot Pod. This software was tested with a Garmin 310XT and is released under GPL ‘as is’.

To use this utility on Windows XP:

• Download the executable from http://fellrnr.com//Utilities/CalibrateFootPod/ParseTCX.exe
• Check the executable for viruses (trust no one!)
• Run with your Garmin 310XT and Foot Pod enabled. I ran with 'speed source' set to 'Foot Pod' rather than 'GPS'.
• Transfer the record of the run to Garmin Training Center.
• Export the record of the run from Garmin Training Center as a 'TCX' file.
• Run the executable ParseTCX.exe passing the full path to the TCX file as a parameter.
  • Open a windows explorer window and navigate to the folder with the TCX file.
  • Right click on the TCX file and select "Open With…" then "Choose Program…"
  • Click on "Browse…" and navigate to where you downloaded ParseTCX.exe from.
  • I would recommend checking the box “Always use the selected program to open this kind of file" so that you can just double click on the TCX file in the future.
  • Click OK
• A command window should open and print out a lot of data. At the end you should have a line that says "average scale N" where N is the scaling factor.
• On your Garmin, multiply your current calibration factor by this new scale. So if your scale is currently 990 and the average 0.94255403, the new scale will be 993.

As always Contact me if you have a problem and I will try to help, but this is provided ‘as is’. You can also download the source code from http://fellrnr.com//Utilities/CalibrateFootPod/ParseTCX.zip
