Introducing the Arc 12!

Join us for the newest race at the Arc of Attrition - Arc 12 - your coastal trail half-marathon.

Brought to you by the team behind the legendary Arc of Attrition by UTMB, this race may be short, but the experience will last long!

New in the 20K category, this race is a great introduction to the coastal trails in Cornwall and perfect for runners looking to begin their Arc experience. Starting from near Godrevy, you'll sample the morning sunrise and stunning scenery as you head for the finish in Porthtowan.
