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.
