What to Expect on GBDURO

GBDURO is one of the UK’s most iconic self-supported bikepacking events, taking riders from Land’s End to John o’ Groats along the legendary GB Divide. Organised by The Racing Collective, the event blends road, gravel, bridleways, singletrack, and ancient trails into a true all-road adventure while promoting a strong ethos of sustainability and low-impact travel.

The route covers approximately 2,000 kilometres with around 25,000 metres of elevation gain, starting in Land’s End, England, and finishing at John o’ Groats, Scotland. Riders follow a fixed GPX route through England, Wales, and Scotland, crossing national parks, remote moorlands, forests, and mountain landscapes on a constantly changing mix of surfaces that rewards versatility as much as endurance.

GBDURO follows a strict self-supported philosophy. Riders are responsible for their own navigation, food, accommodation, and mechanical repairs, with no outside assistance permitted. More than a race, the event encourages participants to embrace the principles of Leave No Trace and #NoFlyRide, making sustainability an integral part of the challenge.

With its varied terrain, demanding distance, and unique environmental ethos, GBDURO has become one of Europe’s most respected mixed-terrain bikepacking events. It is a challenge that rewards resilience, adaptability, and a genuine spirit of adventure.

What bike do I need?

For GBDURO, we'd recommend a Hardtail MTB — plan on 2.2-2.4" Tubeless tires and a wide-range drivetrain, something like a 30-32T (1x) chainring paired with a 10-52T cassette, to handle the terrain comfortably.

GBDURO takes place on August 15, 2026. That puts it in summer, with long daylight hours, though heat can become a real factor.

What surface is it?

GBDURO runs primarily on off-road, and we'd recommend 2.2-2.4" Tubeless tires to handle it comfortably.
