Claim the map
Every run, walk, hike, or ride claims real cells on a live map of your city.

Run, walk, ride, or train — every session claims real territory, builds your crew's strongholds, and levels you up. One account, every sport, one shared map.
Each sport has a role in the same living game, so showing up matters more than being the fastest or strongest.
Every run, walk, hike, or ride claims real cells on a live map of your city.
Team up, hold a district's stronghold, and defend it as a crew.
Outdoor GPS sports, gym sessions, and court sports all build the same account.
Cycling links cells into corridors that keep earning your crew influence over time.
Your exact route always stays private. Only delayed, aggregated territory effects become public.
Common Grounds starts here. Every verified move lights up a game territory, links cities, activates Arenas, and builds a crew strategy no single athlete can carry.

A walk after work, a new running loop, or a weekend ride can change the map. Consistency and exploration matter—not endless distance.

Arena matches, strength work, and recovery all have distinct jobs. A balanced crew of regular people can outplay a team built around one elite athlete.
Common Grounds turns real activity into a simple loop that gives every session a purpose.
Record an outdoor activity, train, or play a real match.
Fair-play checks protect your progress and the shared competition.
