Your GPS draws a perfect line to the finish. It just doesn't know the line is closed on Sundays. UltraPace turns any GPX route into an offline roadbook — resupply stops, opening hours and water points, readable in one glance.
No account · No cloud · No subscription
In an ultra, the rules are simple: no support crew, no private resupply. Whatever you eat, drink or fix, you find along the way. The race isn't won on the climbs — it's won at the petrol station that was actually open.
Your GPS computer is brilliant at one thing: the line. But the line doesn't know that the next shop closes in twenty minutes, that the water tap is 300 metres off route, or that everything in the next 60 km is shut until morning.
So racers fix it themselves — spreadsheets, screenshots, laminated cue sheets, guesswork. Planning that takes evenings, then falls apart the moment you're behind schedule and every opening time shifts.
At hour 21, with a sleep-deprived brain, you shouldn't be doing logistics. Your roadbook should.
UltraPace is two tools with opposite jobs. One uses the internet, once, at your desk. The other never needs it again.
Upload the race route. UltraPace scans open map data along your exact line and builds the roadbook for you:
Install once on your phone, import the route pack, switch to airplane mode. From here it's yours:
Any GPX file from any race or planner. The configurator samples your line every 500 metres and gets to work.
GPX inStops, resupply, water and opening hours are compressed into a single route pack. Send it to your phone — AirDrop, mail, QR.
Route pack outImport the pack into the roadbook app. From that moment it works with zero signal — mid-forest, mid-night, mid-nowhere.
Airplane mode onRest stops every ~80 km and every food source within 200 m of your line — supermarkets, bakeries, fuel stations, fast food. No detours into the unknown.
The roadbook knows chain opening times per day of the week. Shops that will be closed when you arrive simply dim out. CLOSED is a fact, not a surprise.
Over 3,200 public drinking water points, filtered to within 300 m of your route. Empty bottles stop being a navigation problem.
Not "works with weak signal" — works with no signal. The whole roadbook lives on your phone. Test it in airplane mode before the start, then trust it.
Built on OpenStreetMap and open data. Your route never leaves your device. There is no server to go down at km 600 — and no subscription, ever.
Big numbers, high contrast, one screen. Designed to be read in under a second at 28 km/h — so your eyes stay on the road, not on a map.
We're prototyping a companion e-ink display for the handlebar: your next stops, food and water on a screen that's readable in full sunlight and sips battery for days. No backlight burning through your power bank at 3 a.m. — just the four numbers you actually need.
It's early. But it points at what UltraPace believes: the best race tech is the kind you forget is there.
UltraPace started as one rider's preparation for the Race around the Netherlands — 1,900 km, self-supported, against the clock. It became a tool because the spreadsheet wasn't good enough.
If a feature needs a connection mid-race, it doesn't ship. Coverage maps lie; your roadbook shouldn't.
Powered by OpenStreetMap and public water data. Free data in, fair tool out — and every racer gets the same information, exactly as self-supported rules intend.
We measure success in seconds not spent looking at your phone. The goal is a tool you check, not a feed you watch.
UltraPace is in active development, tested on real ultra routes. Leave your email and be first in when the beta opens — and help shape what a roadbook should be.
