GpxTcxWelder Manual

Requirements:

A installed Java SE 6. If you don't have it yet, you can get it for free at http://java.com/

Getting started:
First of all you have to get your Garmin training data in form of a TCX File. If you use the online portal Garmin connect, you can simply select the desired workout and then click the „Export“ Button and Download the TCX-file. Save this file in your local filesystem an remember it's location.

Now start GpxTcxFileWelder by clicking on its icon. Load the previously saved TCX file into the welder application by clicking on the topmost button captioned „Load“. Give a few seconds to load the file.
Now you can see your waypoints in the table „Output preview“. You should see data in the first three columns, but not in the last three columns.

Now load one or more GPX files (It is extremely important, that those files use the GPX version 1.1 – you can convert them with GPSbabel http://www.gpsbabel.org/ if they don't do) which cover the timeframe between the first and last TCX-waypoint. Adjust settings so that they meet your needs. Timezone is only for displaying the data- internally everything is calculated in UTC timestamps.

When you are done loading your data into the application click the „Start processing“ button. The TCX file and the GPX file(s) will now be merged together. At the end of the process you will get a short info if everything was successful.

Now you can save the new file by clicking on “Save”.

You can now upload these file to Garmin Connect. You should now see the GPS track from the GPX file along with your workout data.
