What to Expect on The 360

The 360 is a 360-kilometre gravel event organised by Hidden Tracks Cycling that loops around London, starting and finishing in Greenwich and passing through the surrounding counties of Kent, Surrey, Hampshire, and Berkshire. With 4,400 metres of elevation gain and a mix of bridleways, byways, gravel tracks, and quiet lanes, the route demonstrates that genuinely challenging and remote riding is accessible without leaving the radius of the capital. The premise is partly polemical: you do not need to fly to find adventure. The route deliberately avoids major roads and seeks out the least-trafficked and most interesting surfaces in the London commuter belt, which often means climbing through woodland on muddy tracks, navigating permissive bridleways through private farmland, and descending on chalky North Downs paths that turn unpredictably slippery in wet conditions. The 24 to 36-hour window makes it most naturally a one- to two-night effort, and the event is run in a self-supported format with no feed stations or mechanical support. Hidden Tracks Cycling is a London-based collective with a reputation for finding unexpected riding in familiar landscapes, and The 360 reflects their philosophy of looking harder at what is already nearby before looking further away. The June timing usually means reasonable weather, though the event has run in rain and mud. A compelling option for riders based in the UK who want to test their ultra-distance capacity without the expense or carbon cost of travelling to a continental event.

What bike do I need?

The 360's terrain calls for a Gravel Bike, ideally running 45-50mm Tubeless tires. On the drivetrain side, a 38-40T (1x) chainring matched to a 10-51T cassette gives enough range for the climbing involved.

How difficult is it?

Expect a Moderate-tier challenge at The 360 — fairly flat climbing over rough, technical terrain for a good stretch of the route, with mild and generally comfortable weather typical for the time of year.

When does it take place?

The 360 takes place on June 20, 2027. That puts it in summer, with long daylight hours, though heat can become a real factor.

What surface is it?

The 360 runs primarily on gravel, and we'd recommend 45-50mm Tubeless tires to handle it comfortably.
