Riders unprepared for long periods of self-supported effort, independent navigation, or the mental fortitude required to resist quitting when close to civilization will find this event particularly challenging.
Training focus

FAQs
What kind of bike is recommended?+
A reliable gravel bike or mountain bike is recommended, as both types are suitable for the constantly changing character of the terrain, offering different advantages.
What tyres should I use?+
Tyre choice is weather-dependent; fast-rolling gravel tyres work well in dry conditions, but expect chalk, woodland, and Greensand Ridge sections to become significantly slower and more technical if it's wet.
Is there a time limit?+
There is no strict overall time limit, though fast riders typically aim for a sub-24-hour finish, while others may choose to complete the route as a bikepacking trip over a weekend.
Can I ride just part of the route?+
Yes, the route naturally divides into sectors, and many riders choose to challenge themselves over shorter distances or individual sectors rather than undertaking the full 360 km orbit.
How do I navigate the route?+
Riders navigate using a GPX file provided before the event, ideally on a dedicated bike computer like a Garmin or Wahoo, although phone-based navigation is also used by some.
Is the route fully supported?+
No, The 360 is entirely self-supported, meaning riders are responsible for their own pacing, mechanicals, food, navigation, and all decisions throughout the ride.
