Self-supported
Carry it or buy it on route, the same as any other rider. No pre-arranged support, no crew cars, no private resupply. Shops, fountains and hotels are fair game.
Single stage · self-supported · around a continent
One lap of Europe, tracing the outer edge of the mainland — down the Atlantic, around the whole Mediterranean, up the eastern frontier to the Baltic and home along the northern shore. The clock starts once and never stops.
See the route ↓The route
PERIMETER follows the coastal frontier of mainland Europe, anti-clockwise from the Maas. Where the sea cuts in, the route climbs over it; where the land runs out, it turns north. No shortcuts, no ferries between checkpoints — the whole rim, under your own legs.
Interactive · click the map to zoom · orange dots are the timing checkpoints. The red line is the official track, routed along real cyclable roads — it stays on land the whole way. Every distance and every metre of climbing on this page is measured along it.

There are no official rest days and no neutralised sections. The "stages" below are simply the timing segments between control points — you ride them back to back, sleeping when and where you choose.
The format
Carry it or buy it on route, the same as any other rider. No pre-arranged support, no crew cars, no private resupply. Shops, fountains and hotels are fair game.
The clock starts on the Erasmusbrug and stops when you cross it again. Every minute counts — including the ones you spend asleep.
This is an individual time trial around a continent. Ride your own race; riding in another's slipstream is not permitted.
Everybody rides the identical route — the official GPX is the race. Leave the line only for food, water, shelter or safety, and rejoin exactly where you left it. No personal shortcuts, no variations.
A GPS tracker broadcasts your dot for the whole race. Dot-watchers, and the safety desk, never sleep.
Beyond the cutoff you are still welcome home, but off the clock. The generous window is there to be used — ride it at a pace your body can carry all the way round.
By the numbers
The pace
The clock runs for 60 days, from the Erasmusbrug back to the Erasmusbrug. Spread across the whole route, that is the effort you have to sustain — climbing, weather and sleep all included.
Committee note The organisers actively encourage riders to plan in slow, relaxed recovery days. The generous window exists so you can soft-pedal, sleep in and take a full rest day whenever your body asks for one — build a few easy days into your plan and you simply ride a little quicker on the days you do roll.
