Very good physical condition and experience in trail running is a prerequisite for mastering the different distances. The participant must be able to complete the distances in a partial autonomy (partial self-sufficiency) according to the ethics in trail running. We reserve the right to exclude people from participation.

When registering for the E250 distance, at least one Ultra Trail (min. 100km) finished since 1st january 2024 must be given as a reference or the runner must have a UTMB Index of the category 100K or 100M. The organisation reserves the right to check references.

For the races E101, E51 and E35, a lottery will be held. Runners will have to pre-register on Eiger Ultra Trail by UTMB between Monday, 21 September 2026 at 10:00 am CEST and September 28, 2026 at 11:59 pm CEST. Participation in the lottery is for free.

Lottery results will be available in your myUTMB account on Wednesday, 30 September 2026. The follwing results will be communicated:

• Positive draw: Please register by 5 October at the latest. Otherwise, your spot will be forfeited.

• Waiting list: All runners with “Waiting List” status will automatically take part in the second lottery on 6 October.

• Negative draw: If you have not been selected in the lottery twice in a row, you will receive a guaranteed spot for the 2028 edition, without having to enter the lottery again.
  
  The time of registration has no influence on the draw. Participation in the lottery for E101 requires a valid UTMB index.

  The following forms of participation are possible:

  • single  
  • Mini group  

  It is not permitted for a person to register several times or for several distances or in different forms of participation. It is not permitted to register as single and in a mini group in one or several mini groups. A Mini-group consists of 2 – 5 people. Members of a group do not have to register for the same route. The Mini-group format is only for the lottery, every runner will start as an individual runner in the race. Multiple registrations will be ignored.

  If a lottery winner does not duly confirm their participation by paying the entry fee by Monday, 5 October 2026, 11:59 pm CEST, they will forfeit their right to a starting place.

  A starting place right is also cancelled if a lottery winner transfers the starting place right to another person.

  The unlucky entrants will also be notified in their myUTMB account. The organiser reserves the right to hold a second draw for the E101, E51 and E35 distances on Tuesday, 6 October 2026. All entrants with the lottery result "waitlist" will automatically take place in the second draw.

The draw will take place in accordance with the timetable. The participants will be informed to this effect. The draw will take place by form of participation and nation.

The forms of participation will be taken into account according to the percentage of incoming registrations. All members of selected mini groups will receive a ticket.

Examples: 65 per cent of registrations are for single starters. 35 per cent are for people in mini groups. Therefore, 65 per cent of the starting places will be issued among the single starters and 35 per cent among the mini groups.

To promote trail running in Switzerland, at least 30 per cent of the E101, E51 and E35 starting places are available to persons of Swiss nationality. The starting place quotas for Swiss runners will apply to the starting places in the lottery and also to the guaranteed rights to a starting place.

In order to celebrate international trail running, there will be two guaranteed starting places for each nation entered for a distance. Nations will not be taken into account in the mini groups lottery form.

Examples: Only one person of “xy” nationality registers. He/she receives a guaranteed starting place. As soon as more than two people of the same nationality register, they are all entered into the lottery. Their nationality is checked.   The time of registration has no influence on the draw. Participation in the lottery requires a valid UTMB index from any UTMB category.

In order to give fair recognition to high level athletes and to ensure a fair management of entry applications, we reserve places for elite athletes according to their Performance Index in the category of the race they chose to compete. Elite runners must register during the registration period. No registration will be accepted after the deadline.

If the distance is lottery based, the elite runners must register at the same time as other athletes.

Once a distance is sold out, the event organiser has the right to refuse an elite registration.

All elites must register to a race at least 60 days before the race. See the requirements to qualify as an elite athlete here: Elite Runner Registration Benefits
