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 2022 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 September 22, 2025 at 12.00 noon CEST and September 29, 2025 at 23.59 CEST. Participation in the lottery is for free.

Results of the lottery will be communicated to runners on October 1, 2025 via an email coming from Trail Run Series Europe.

Runners will have time until October 6, 2025 at 23:59 CEST to confirm their registration by completing the registration form received in the email (personal link).

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 starter  

• 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 for a single starter to also register 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. Multiple registrations will be ignored.

There will be a draw for the 2025 E101, E51 and E35 registrations. The winners will be informed by e-mail mail from the sender Trail Run Series Europe with a personal and non-transferable registration link.

If a lottery winner does not duly confirm their participation by paying the entry fee by Monday, October 6, 2025, 23:59 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 by email from the sender Trail Run Series Europe. The organiser reserves the right to hold a second draw for the E101, E51 and E35 distances on October 7, 2025.

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 starting places and 50% of the 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.

Runners will have time until October 6, 2025 at 23:59 CEST to confirm their registration by completing the registration form received in the email (personal link).   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.
