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).

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.
Every step makes a difference
By taking part in 100km in 30 days, you are helping the Marie Keating Foundation provide free, life-saving cancer information, support services and community outreach to thousands across the country.
