Run together.
Run together.
See every runner live.
corun puts your whole group run on one live map: who is running, who has stopped, who has wandered off-route and who needs help — designed for 2,000 runners per event.
Runners: open the link your organizer shared. No account needed.
How it works
From link to live map in three steps
No hardware, no bibs to scan. Runners share their location only while the event is live.
Share one link
Send corun.in/e/… or the QR code. Runners join in the Android app with
one tap.
Watch it live
Start the event and see everyone on the map. Stopped and off-route alerts come to you first. SOS is coming soon.
Features
Built for run-day safety
Everything the organizer needs on one screen, on a laptop, a tablet or a phone.
SOS in 3 seconds coming soon
Runners will press and hold for 3 s. You see who, where and when, and acknowledge it from the map.
Live map — designed for 2,000
Every runner as a dot with status: running, stopped, off-route, paused, finished.
Stopped & off-route alerts
Grouped alerts so you can triage fast and acknowledge in bulk.
Pause, not quit
Runners can pause sharing for a break and resume with one tap. You keep their last-known spot.
Trail setup — free
Upload a GPX or draw the route; set off-route tolerance. Free for every organizer.
Finish pin & safety net
Optional finish pin; the event auto-ends if it is forgotten (12 h after start or 2 h idle).
