Event Details

The event basecamp is at Rock UK, which also provides onsite catering. Parking is available on-site for a fee. Overnight accommodation in various lodges and shared rooms is available for booking through Rock UK for the nights before the event.

A mandatory kit list includes sufficient nutrition and hydration, weather-appropriate clothing, dry clothes for after the race, a mobile phone, and a headtorch.
