Arc 25

Runners will complete a point to point 25 mile course along the Cornwall Coast Path, part of England's longest marked footpath and a National Trail. The Arc 25 race starts near St Ives, before descending to join the trail and take runners across a variety of coves and terrains before arriving at Porthtowan.

The exact start location of the Arc 25 will be announced later in 2024. The total course length will be approximately 40 - 45km.

Particular care needs to be taken at the following points to ensure you follow the official coast path.

• Hayle
• Mexico Towans
• Dunes of Doom
• Godrevy Head

There are two sections where minor route deviations are allowed from the official coast path. These are:

• Headland around St Ives Island
• Portreath

The Cornwall 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.
• warm second layer A warm second layer top with long sleeves (cotton excluded) of a minimum weight of 180g (men's size medium) OR the combination of a warm long-sleeved base layer of a minimum weight of 110g (men's size medium) and a durable water repellant (DWR protection) windproof jacket. The windproof jacket does not replace the mandatory waterproof jacket, and vice-versa
• Long-legged trousers or race leggings OR the combination of leggings and socks, which must cover the legs completely (these can be carried in the running pack in case their use is necessary).
• Waterproof over-trousers The seams must be sealed or fully taped. They do not replace the long-legged trousers or race leggings.

It is recommended that this is downloaded before arriving at the event. The event's emergency contact number (available in the Runner's Guide) must be saved in your phone contacts. Do not mask your number. Ensure you start your race with a fully charged battery. An additional, external battery is highly recommended.

• Capacity to carry a minimum of 1.5 litres of fluid At the departure of some aid stations it will be mandatory to leave with 1.5 litres of fluid (water, energy drink etc.) depending on the section to be covered or the weather conditions.
• 2 x fully functioning head or hand torch Each torch must have a spare, separate cell or set of batteries. Power banks are permitted as a spare battery. However each torch must have their own powerbank or set of batteries. At least one torch must have a minimum 200 lumens brightness.
• Red tail light (to be switched on and worn on back of pack at all times) Any red tail lights attached to headtorches do not fulfil this requirement.
• Survival bag or emergency bivvy bag This must have minimum dimensions of 2.0m x 0.9m. It is recommended this is a thermal bag which retains body heat. A survival blanket or foil blanket is not acceptable.
• Emergency food reserve Recommendation is a minimum of 800 kcals (2 x gels and 2 x energy bars)

• Synthetic insulation mid-layer or gilet To keep warm while resting at aid stations.
• Personal first aid kit Including a minimum of blister plasters, cleansing wipes, dressings, paracetamol and personal medication etc.

On certain sections of the course, the use of poles may be prohibited for safety or environmental reasons.. In such cases, it will be indicated by specific signs along the route.

If you choose to take poles they must be carried for the duration of the race. It is forbidden to start without poles and obtain them during the race. Equally, you cannot start with poles and then put them into your drop bag. Poles are not allowed in your drop bags.

Music: listening to music using earphones, is tolerated, so long as it is safe to do so. All earphones MUST be removed when crossing any roads, as well as on approach to, and while at, aid stations and when in conversation with staff and volunteers.

COLD WEATHER KIT (EXTRA ITEMS)

The following items are only mandatory if the cold weather kit is made compulsory by the Event Director.

• Protective clear lens eyewear. It is possible to use the same glasses as sunglasses if they are glasses with photochromic lenses.
• Second warm layer. An intermediary layer between the first layer and waterproof jacket. It is recommended this is a high-loft jacket or smock featuring synthetic insulation (e.g. Primaloft or Polartec garments).

There will be two aid stations available at strategic locations along the course. These provide basic food and drink options to runners, warm shelter and toilet facilities. A selection of other snacks and ultra-fare, including cold drinks, water and cola will be available.

There will be toilet facilities (including female only toilets), seating and rest areas.

There is no personal assistance ('support crew') allowed during the Arc 25 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 25 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.

Although it follows an existing way-marked route, and there will be some course waymarking, we would recommend runners have previous trail running 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. You should ideally have had some experience of night time running prior to the event.
