Athletes that take part in this Challenge will receive the gift of fitness (and potentially some digital milestone badges).
If you achieve the 105 km milestone, the badge will appear in your Trophy Case.
The Challenge starts and ends based on each runners local time zone.
Manual entries, treadmill runs, or runs marked 'Private' will not count towards your Challenge effort.
All activities logged during the Challenge period must be uploaded to Strava no later than three days after the Challenge ends.
