|---|---|

| Arc 25 | From £95.00 - £125.00 |
Prior to the event, all participants must have read and understood the event rules including the mandatory kit needed to be carried at all times during their race.
Races are open to anyone, male or female, who are at least 20 years old on the day of the race start:
- Arc 100. Born on or before 24 January 2005.
- Arc 50 and Arc 25. Born on or before 25 January 2005.
To register to the Arc 100 and Arc 50, runners must have experience in long distance races. It is important to have in mind the difficulty of the terrain and the fact these are semi-self-sufficient races. Arc of Attrition by UTMB® is not an event for beginners in trail running.
Arc 100:
The organisers recommend participants to have a UTMB® Index, that means a level of performance, of at least 380 in the 50K, 100K or 100M race category, to register for the Arc 100. This is the value at which the cut-off times are calculated. With an UTMB® Index below this value it is very likely the runner will not be able to arrive at the checkpoints on time as they will not be able to comply with the established cut-off times. It is advisable not to register for Arc 100 with a UTMB® Index below 380. Cut-off times are strictly enforced.

Arc 50:
Participants registering for the Arc 50 do not need to have a UTMB® Index. However, the race still features difficult terrain and the potential for challenging weather conditions. Participants will need to meet the cut-off times in order to continue in the competition. Despite not requiring a UTMB® Index, participants must be prepared, both physically and mentally, for the race.
Arc 25:
Participants registering for the Arc 25 do not need to have a UTMB® Index. However, the race still features difficult terrain and the potential for challenging weather conditions. Participants will need to meet the cut-off times in order to continue in the competition. Despite not requiring a UTMB® Index, participants must be prepared, both physically and mentally, for the race.

- 40km (25 miles) / 80km (50 miles) / 160km (100 miles) of stunning trail-running on the undulating South West Coast Path.

A) Cancellation insurance
Runners are offered the option to subscribe to cancellation insurance during the entry process. The purpose of the cancellation insurance is to reimburse registration fees paid for the 2025 edition of Arc of Attrition by UTMB® in the event a participant requests to cancel their registration as long as the reason for cancellation is included in the policy. If you intend to take out cancellation insurance, it must be purchased with your registration.
Runners who wish to subscribe to the cancellation insurance will be asked to pay an additional 10% of the total amount, to be added to the registration fee. Cancellation insurance must be booked exclusively at the time of registration.
We recommend you read the 'General Terms & Conditions' before cancelling your registration. If you wish to apply for a refund you will need to complete the online claims form. Please note: cancellation insurance and the claims process are not managed by UTMB or Arc of Attrition.
There will be no refund for runners who wish to cancel their registration and do not have cancellation insurance.
Please note: we do not offer deferrals to a future edition of this event under any circumstances other than those outlined within our UTMB World Series Pregnancy Policy.
B) Exceptional conditions in case of event cancellation
If a race is cancelled, or if the event needs to be organised differently (e.g. one or more races are cancelled), for any reason beyond the control of UTMB Group, more than 30 days before the start of the event, runners will be partially refunded. The amount of the refund will be decided as to allow UTMB Group to deal with the irreversible expenses incurred at the date of the cancellation.
If a race is cancelled less than 30 days before the start of the event, or if a race in progress is interrupted, for any reason beyond the control of UTMB UK, entry fees will not be refunded.
A) Transfer to another runner
Your registration for Arc of Attrition by UTMB is personal and non-transferable. We do not allow the transfer of a registration to another runner. Therefore, if a runner is unable to attend, they will only be entitled to a refund if they have taken out cancellation insurance and the reason for cancellation is included in the policy. Refunds are managed externally to UTMB.
B) Transfer to another race in the same event
It is possible to change from one race to another race of shorter distance up to one month before registrations close, if registrations are available in the competition. However, the difference between registration fees will not be refunded.
It is also possible to request a change of competition to a race of a longer distance if there are registrations available. This change will not be made automatically, and it will be up to the race organisers to decide whether to accept it or not. In this case, the runner will have to pay the difference in price. The price will be the price in force at the time of the acceptance of the change by the organisation.
Participants cannot change their registration into a competition which is full.
To give fair recognition to high-level athletes and to ensure a fair management of registration requests, we reserve places for elite athletes across each race, who request an entry, according to their UTMB performance index.
Elite athletes must contact Arc of Attrition by UTMB® by e-mail (arcofattrition@service.utmb.world) before the registration closing date. Registrations will not be accepted after this date. If a race is sold-out, the organisers reserve the right to accept or reject the registration request.
An elite athlete must have the following UTMB Index on the day they request a registration. These are specific to each race category (50K / 100K / 100M) and should be noted before requesting an entry. Elite athletes who do not meet the minimum criteria will need to complete the registration process as normal.
