Your 100km in 30 Days, Step by Step

1. Register

2. Get out there

Any activity counts.
Walk, jog, swim, cycle, wheel or move in whatever way suits you, just build up the distance throughout June.

3. Log Activities

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

4. Challenge

Go solo, join a team, or rally your own crew.
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.

Prizes to win...

By signing up and taking part in the 100km in 30 Days challenge, participants will have the chance to win a range of prizes throughout the campaign, thanks to the generous support of our partners and supporters.

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.
