For session with GPS tracking, myGeonaute lets you export your session into a standard GPX format compatible with the majority of GPS activity analysis and sharing sites.

To download your file, go to the “Activities” tab then to the session that you want to get a file from. Click on the “Actions” menu (located to the right of the session title)

then click on "Export in GPX format":

The file is therefore saved in the default download menu of your web browser.

The way you access downloaded files from the internet depends on your browser. The file often appears at the bottom of your internet window or in the "downloads" menu of your web browser.

Then you just need to upload this file to the site of your choice.
