The Gravel Tro Breizh is a fully self-supported, off-road ultra-distance bikepacking event across Brittany, covering approximately 1,300 km from Lac de Trémelin and allowing gravel, monstercross, or mountain bikes.
What this race demands
This 1,300 km self-supported off-road ride with 20,000 m of climbing demands sustained power, climbing endurance, and the ability to manage effort and fueling over multiple days. The long distance makes pacing and durability central to finishing.
Climbing endurance
The route has 20,000 m of elevation gain across 1,300 km. Riders need to sustain climbing effort while preserving energy for the distance still ahead.
Off-road durability
The event is described as off-road and allows gravel, monstercross, or mountain bikes. Riders must tolerate prolonged riding on off-road terrain, though the specific surface conditions are not stated.
Multi-day pacing
At 1,300 km, this is an ultra-distance ride likely to take several days. Managing effort and recovery across that duration is essential.
Self-supported management
The event is fully self-supported, so riders must manage their own needs during the ride without event-provided support.
Because this ride is likely to last several days, plan to consume roughly 60–90 g of carbohydrate per hour while riding, adjusting to what you can tolerate.
