Arc of Attrition 100 mile

The races have a strict cut-offs. With checkpoints approximately 20 miles apart, competitors will need the ability to be self-sufficient for long periods of time.

As safety is our primary concern, competitors will need to carry mandatory kit at all times and will be subject to random kit checks throughout the event. We would strongly recommend and advise the use of your own support crew.  The cost of entry includes the hire of a compulsory GPS tracking device which allows race HQ (and your friends and family) to track your progress online throughout the event.

Although it follows a way-marked route, this is a self-navigation event and ONLY suitable for experienced ultrarunners.
