The Ardennes Monster, the ultimate ultracycling challenge in the Ardennes.
1 050 km – 20 000 m + | 500 km – 8 848 m +
Created in 2022 by the team who designed The Conquest of the Ardennes, the event brings together two bikepacking routes designed for ultra-distance cyclists:
- The full loop: 1 050 km across four countries – Belgium, Luxembourg, Germany, and France – with 20,000 m of bold elevation gain.
- The half: 500 km and 8 848 m of elevation, equivalent to the Everest Mount, climbed in the Ardennes.
From the legendary climbs of Liège–Bastogne–Liège to the hidden cols of the Eifel, the route connects mythical classics, forest roads, and remote valleys. Every climb, every turn, every night ride by headlamp is an odyssey within yourself.
