Bell countdown.
A clock the size of your screen with your buffer to the next start. Voice calls at 3, 2 and 1 minutes, even with the screen off.
One loop. Every hour. Until one is left.
The race companion for backyard runners, their crew and the people who run the race.
Every hour,
fewer.
Twelve start. The bell rings on the hour. Whoever is not in the start corral when it rings is out.

Four rules.
No exceptions.
Every hour, on the hour.
The bell rings at the top of every hour. Everyone still in leaves the corral together.
6.706 km per loop.
Same loop, every time. Twenty-four of them make 100 miles.
Back before the bell.
Finish inside the hour. Whatever time is left is yours: food, rest, fresh socks.
One is left.
Miss a start and you are out. The last runner finishes one more loop alone to win.
What the app does.
Crew live view.
Your crew sees you on the loop and when you will be back, usually within two minutes. The bottle is ready before you are.
A pacer that learns.
It learns where you walk and where you run, in 50 m pieces, and tells you live whether you are ahead of your target loop time.
Fuel per loop.
One tap logs what you ate. Carbs, sodium and fluid per hour, and a nudge to your crew when salt runs low.

Questions.
When can I use it?
The Android app is in testing now and waitlist invites go out in small groups. The iPhone app follows; until then the web version runs in the iPhone browser.
Does it need signal on the course?
No. Countdown, pacer and voice calls run on the phone itself. Your crew view catches up as soon as the signal is back.
Is there AI in it?
No. Everything is plain arithmetic on your own loops, so it still works at 3 a.m. in a dead zone.
Which watches work?
Apps for Garmin and Wear OS are built and being tested on real watches. They show the loop count and the time to the bell.
What happens with my data?
We never sell your data. The servers are in Germany. Your crew only sees you during a race you share with them.
Is this the app of a specific race?
No. It is an independent app for any race in the backyard format, big or small.
