Any activity counts.

3. Log Activities

Track your progress with a dedicated activity dashboard that integrates with Strava, Fitbit, and Garmin (or manually log your steps).

Every step, pedal and push adds to your total and your ranking. Keep an eye on the leaderboard - you never know who’s catching up.

Your challenge, your way

There's no set route and no strict schedule - you can complete your 100km however and whenever it suits you throughout June.  

Whether you’re flying solo or pushing each other on as a team, every kilometre matters — daily walks, weekend cycles or whatever gets you moving.

Join thousands of people this June and make your movement matter.
