Offline race timing · Built for trail

Race timing for where the signal ends.

Bibsee times your race on its own little network. Volunteers record bibs on iPads, runners check their results at the finish tent, and not one bar of signal is needed.

Seven out on the ridge, a hundred and forty-two home. Bibsee keeps that count for you, from the first start to the last runner in.

Bibsee on the local network A router, and below it four iPads grouped around the Bibsee box. Wi-Fi signal passes from the router down to the group and from the group back up. The router's link to the internet is cut; nothing needs it on race day. INTERNET not needed on race day ROUTER IPADS BIBSEE

Cell service ends at the trailhead.

Most trail races start where the pavement stops. Bibsee brings its own network, so timing works wherever your finish line ends up.

On course

Know who’s still out there.

At the end of a long day the question isn’t who won. It’s who hasn’t come in yet. Bibsee always has the answer.

Everything the finish line needs.

One small box, the iPads you already own, and a sign for the finish tent. That’s the whole kit.

The box

Fits in the finish-line tote.

Bibsee runs on a Raspberry Pi 500, a whole computer tucked inside a keyboard. Set it on the timing table, plug it in, and you’re timing.

Zero bars. Full results.

Timing works the same at a remote trailhead as it does downtown.

Bring the iPads you already have.

Volunteers open a page and start recording. Nothing to download, nothing to update the night before.
