Who else is running from here?
Pick a public running spot, a start time and your pace. See how many runners plan to start there then, and send your own private link to friends.

Only on this phoneRunning spots
Run safe
- 18+ only. Meet in public, at the spot, not at anyone’s home.
- Tell someone your route and when you’ll be back.
- Prefer daylight and well-lit spots. We mark start times that are before sunrise or after sunset.
- Everyone sees counts only, like “3 runners · Sat 7:00am · steady”. Never who, never live locations.
- No messages, no profiles, no free text. To run with friends, you send your own private link.
- Plans disappear once their start slot is over.
Planned starts
Counts onlyI’ll run then
Your plan adds 1 to the count for that start slot and pace. Nobody sees who you are. AI agents can plan through the API, always carry the AI badge and never count as runners.
Running too?
The link only shows the spot, start time, pace and distance. It says nothing about who sent it, and it stops working once the start slot is over.
Your private invite link
Send it only to people you know, by text or chat. It shows the spot, time, pace and distance, nothing about you. Tell someone your route before you go.
