Whether you're new to trail running or looking for a fast and rewarding challenge, the Arc 20K offers an unforgettable adventure on Cornwall's wild winter trails.
Runners will complete a new undulating 22 km loop along the South West Coast Path, a National Trail and one of England's longest marked footpaths.
The Arc 20K race starts at Perranporth Airfield, heading south on the coast path through St Agnes as far as the aid station at Porthtowan. In a first for the Arc of Attrition, 20K runners will loop back North, inland, taking in spectacular views and summiting St Agnes Beacon before heading back to Perranporth Airfield.
For a full list of the mandatory kit (clothing and equipment) which you must have with you at all times during your race, please visit the mandatory kit webpage.
There is one aid station available at Porthtowan, approximately halfway along the route.
This aid station will provide basic drink options to runners, warm shelter and toilet facilities. A selection of other snacks, including cold drinks, water, cola and Näak Energy products, will be available.
There will be toilet facilities (including female toilets and toilets with period products), seating and rest areas.
There is no personal assistance ('support crew') allowed during the Arc 20K competition. Therefore, only participants will be allowed access to aid stations.
The Arc of Attrition by UTMB is a semi-autonomous / self-sufficient event with aid stations and medical cover at strategic locations on the course.
There will be no personal assistance (also known as 'support crew') allowed during the Arc 20K competition. No personal assistance is allowed at any point along the route or during the race.
However, due to the extent of the course, the likelihood of fatigue and the time of year, we strongly advise you to have someone meet you at the finish who can drive you home after the event.
The race follows an existing waymarked route, and there will be some course waymarking. We would, however, recommend that runners have previous trail running experience and are comfortable with coastal path conditions, including climbs and descents with multiple steps.
The route follows the undulating cliff path and cliff edges, and the terrain can be difficult, steep and arduous in places.
