MudCrew presents: The "Raidlight" Arc of Attrition - the South West's toughest ever footrace.

The Arc of Attrition is an extreme winter 100 mile footrace with competitors running in challenging winter conditions.

The Arc is a point-to-point race from Coverack to Porthtowan taking in 100miles of stunning and dramatic Cornish Coastpath, and will complete an Arc around the entire south west foot of Cornwall.  The race has a strict 36 hour cut-off with additional checkpoint cut-offs on route. With checkpoints approximately 20 miles apart, competitors will need the ability to be self-sufficient for long periods of time.

The event carries 5 points towards UTMB qualification.

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 race starts at 12.00 noon on Friday 1st February 2019 and competitors will be bussed to the start area from the race HQ at the BlueBar Porthtowan

Although it follows a way-marked route, this is a self-navigation event and ONLY suitable for experienced ultrarunners. There is an entry requirement of at least a 100km finish and considerable experience of night time running. We reserve the right to refuse an entry if we believe you do not have the right level of experience to compete in this event safely. If this is the case we will refund any monies paid in full.

All competitors will receive an event hoodie at registration and all finishers will be awarded an exclusive and much coveted MudCrew 100mile buckle.

For further details, please see and download the event guide or you can contact us through social media.

Complete The Arc of Attrition and Become a Legend !
