London Orbital Gravel Challenge

Gravel | Cyclocross | MTB bikes | 360 km Gravel Challenge

The capital’s own ultra-gravel adventure.

You don’t have to cross continents to find the edge. The London Orbital Gravel Challenge is London’s local ultra — a 360 km loop that pushes through woodland, farmland, and forgotten backroads to circle the city in one relentless, beautiful line.

It’s everything you expect from an ultra-gravel ride — isolation, exhaustion, and the quiet satisfaction of endurance — all hidden in plain sight, just beyond the M25.

The Ride

• 360 km of mixed terrain — from chalk trails and forest singletrack to rough farm lanes and river paths.
• 4,400 m of elevation — a brutal reminder that London’s outskirts are anything but flat.
• 30 climbs — steep, sharp, and stacked against you.
• Self-supported — no feed zones, no support car, no shortcuts.
• Start/Finish: Greenwich. One full loop. One simple rule: complete the circle.

Legends of the Loop

Last year, only two riders made it round.
This year, five riders completed the full 360 km in under 22 hours — a testament to what’s possible when grit outlasts sleep.

They rode through dusk and dawn, over gravel, mud and tarmac, carving their names into London’s wildest challenge.

Why It Matters

Because this is our ultra.
Not a far-flung expedition or a curated experience — just pure London grit. A ride that starts on familiar ground and ends somewhere far beyond it.

You’ll see the city fade behind you, replaced by trails that feel untouched, climbs that feel endless, and moments that make the whole loop worth it.
