As per the video at about 5:08 in they claim they don't have the internet to upload the data? Then how the heck are they posting these videos and blog updates?
When I finish a run it automatically syncs to Garmin connect and Strava. Assume TomTom does the same. Sync with the computer with the charging cable that is on the internet you are using for this video and blog posts if you must.
As is often said, if it isn't on Strava it didn't happen! Heck, Strava would probably even want to sponsor this.
