Experience 50 miles of the UK's finest coastline
Arc 50 is a challenging point-to-point race from The Minack Theatre, Porthcurno to Porthtowan taking in 50 miles of stunning and dramatic South West Coast Path. By passing Land’s End it will complete an 'arc' around the extreme south west tip of Cornwall.
Arc 50 has a strict 15.5 hour time limit with additional checkpoint and safety cut-offs on route. Runners will need the ability and experience of being self-sufficient for long periods of time in potentially extreme weather conditions.
Runners will complete a point to point 50 mile course entirely along the South West Coast Path, part of England's longest marked footpath and a National Trail. The Arc 50 race starts at the spectacular open air Minack Theatre, Porthcurno and finishes at Porthtowan.
Particular care needs to be taken at the following points to ensure you follow the official coast path.
- Cape Cornwall
- Botallack
- Zennor Head
- Hayle
- Mexico Towans
- Dunes of Doom
- Godrevy Head
There are three sections where minor route deviations are allowed from the official coast path. These are:
- Headland at Cape Cornwall
- Headland around St Ives Island
- Portreath
The South West Coast Path is a stunning location for trail-running.
However, the weather can change within hours and without any warning, especially during January when Arc of Attrition by UTMB takes place. Coastal conditions can be extremely challenging and potentially dangerous if you are not fully prepared. If you are involved in an incident and need to remain on the course while you await help, your clothing and equipment must allow you to remain warm and safe for several hours.
We strongly recommend you test your kit while training in different weather conditions before arriving at the event to ensure your clothing and equipment is suitable.
Your mandatory equipment (including the cold weather kit if required) will be checked before you are issued with your race bib.
All runners must wear or carry the mandatory equipment at all times during the race. Your mandatory equipment must be with you for the whole duration of your race even if you do not use it. Failure to produce an item of mandatory equipment when requested by an event official will result in a penalty or disqualification.
BASIC MANDATORY KIT
- Suitable trail-running footwear Road-running or barefoot style shoes are not acceptable.
- Waterproof jacket with hood This must withstand bad weather on the coastal paths in winter and be made of a waterproof (10,000 Schmerber) and breathable (RET recommended inferior to 13) membrane. The jacket must be fitted with an integrated hood, or one which is attached to the jacket by the original system designed purposely by the manufacturer. The seams must be heat-sealed or fully taped. The jacket must not have any sections which are not waterproof. Air vents designed and fitted by the manufacturer (i.e. under-arm) are permitted, since they do not damage in any obvious way the impermeability. It is the runner's responsibility to judge, with these criteria, if their jacket meets the mandatory kit requirement and is suitable for bad weather along the coast. However, during an inspection, the judgement is made by the official in charge of the mandatory kit check or any random kit check on the route.

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 at least three hot food options, hot drinks and a selection of other snacks and ultra-fare, including cold drinks, water and cola.
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.
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.
In addition, Arc of Attrition by UTMB will have several mobile support crews (Arc Angels) shadowing front, mid and rear runners for the duration of the event. Arc Angels will be found at suitable access points between the aid stations. Each crew will have emergency water, cola, gels and nutrition.
With larger aid stations approximately 20 miles apart, runners will need the ability to be self-sufficient for long periods of time.
There is no personal assistance ('support crew') allowed during the Arc 50 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 50 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 to meet you at the finish who can drive you home after the event.
Arc 50 runners will receive a when collecting their race bib, will receive 1 x 30-litre bag.
After filling them with the items of their choice and closing them, they can drop them in at bag drop near the start line. The bags are then taken organization to the St Ives Aid Station only.
How to get your bag: The bags are returned to either the runner or a family member or friend, only upon presentation of the race-bib. The bags must be retrieved no later than [1 hour after the end of the race]. After that time, the runner must come, in person, to retrieve their bag at the organization headquarters in Porthtowan.
The organization will take the bags of runners who drop out, on condition that their withdrawal is registered. The return time of the bags will depend on logistical factors. Because of those factors, the organization cannot guarantee that all bags are brought to Porthtowan before the end of the race.
Only bags supplied by the organization will be transported.*
Poles are not allowed in these bags. As the items in the bags are neither checked nor controlled, we will accept no claims on that matter. We recommend not to put any valuable items in the bags.
We advise you to keep toiletries and spare clothes in Porthtowan.
*For logistics reasons, UTMB® World series events only accept the UTMB® World series spare bags that are distributed during the check-In. Those bags are reusable, so we ask the runners who already have received one of those bags to reuse it each time they take part in a UTMB® World Series event.
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.
Depending on your pace, the later part of this race will be undertaken in the dark at night. You should ideally have had some experience of night time running prior to the event.
