The Marathon Arcade
Train for your marathon — strength and steps that stick
Every big marathon and half — one browsable arcade. Pick your race, stake on daily steps and strength, and get paid when you follow through.
Cadoo does not time the course. These games are the weeks of work before the start line — steps from your phone, squats on camera.
Start a training game
Templates for your training group: pick one, set the stake, invite your crew. Verify from your phone. Get your stake back — plus winnings — when you follow through.
Daily Steps Streak
Hit a daily step goal in the weeks before your marathon. Miss a day, lose your stake.

What organizers get
For Marathons & Half Marathons, the weeks before the start are the product.
- Participants arrive ready. Cadoo verifies the training — camera reps and device steps — not the race-day result.
- Invites bring friends who were not signed up. A shared clip opens the training game for someone who had not joined.
- Skinned clips spread the event. Skins sit on the clips. Winner cards are for standout finishers, not every workout. In-store redemption is not live.
