To expand a bit on on slug's question, would it be possible to upload tracks from gps devices other than the Garmin Edge?
(I have a Garmin ETrex Vista HCx, from which I can save tracks in .gpx format)
Unfortunately, we don't support the eTrex Vista yet. We will support more devices as we move forward and the eTrex is the most commonly asked about device, so it might come next?
