Join us for the legendary Arc 100
Arc 100 is a unique point-to-point race along the most exposed sections of the South West Coast Path in England's South West. From Coverack to Porthtowan, runners will experience the stunning and dramatic 'arc' of Cornwall.
Arc 100 has a strict 36 hour time limit with additional checkpoint and safety cut-offs on route. With large stretches of coastline between aid stations, runners need the ability to be self-sufficient for long periods of time.
Runners will complete a point to point 100 mile course entirely along the South West Coast Path, part of England's longest marked footpath and a National Trail. The Arc 100 race starts at Coverack and finishes at Porthtowan.
Particular care needs to be taken at the following points to ensure you follow the official coast path:
- Kynance Cove
- Cape Cornwall
- Botallack
- Zennor Head
- Hayle
- Mexico Towans
- Dunes of Doom
- Godrevy Head
There are four sections where minor route deviations are allowed from the official coast path. These are:
- Kynance Cove
- Headland at Cape Cornwall
- Headland around St Ives Island
- Portreath
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.
Aid stations will be available at strategic locations along the course. These provide basic food and drink options to runners, warm shelter and toilet facilities.
Larger aid stations will be well stocked with hot food options, hot drinks and a selection of other snacks and ultra-fare, including cold drinks, water, cola and Näak Energy products.
There are toilet facilities at all locations (including female only toilets). All larger aid stations are located in existing buildings, are warm, and will have seating and rest areas.
In order to keep the larger aid stations exclusively for participants, no personal assistants ('support crew') will be allowed to access the large aid stations at any time for any reason.
Larger aid stations are located in residential areas and we would ask participants to respect our local neighbours and keep all noise to a minimum. Running poles should not be used in residential areas at night.
With larger aid stations approximately 20 miles apart, runners will need the ability to be self-sufficient for long periods of time.
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. However, due to the extent of the course and the time of year, we strongly advise you to have your own support crew. Your support crew will be able to provide you with assistance at designated locations.
We recommend your crew have their own transport and are contactable by mobile phone during the weekend. We will ask you for their contact details when you register.
Your support crew would be useful to pick you up in case of drop out or injury. We also strongly advise you to have a supporter to drive you home after the event. Due to the fatigue of completing Arc of Attrition by UTMB, runners should not attempt to drive themselves home.
Although it follows an existing way-marked route, and there will be some course waymarking, we would recommend this race is suitable only for runners with previous ultra distance experience.
The route follows the undulating cliff path and cliff edges, and the terrain can be difficult and arduous in places.
Large sections of this race will be undertaken in the dark at night. We recommend you have experience of night time running prior to the event and include this in your training.
It is recommend participants have a UTMB® Index, that means a level of performance, of at least 380 in the 50K, 100K or 100M race category. This is the value at which the cut-off times are calculated.
