Regulations and conditions
Updated 08.04.2025
These regulations and conditions apply to participation in the ultra-trail race Oslo Bergen Trail, organized by the voluntary organization Langt og Lenge. The website of the race is oslobergentrail.com.
Oslo Bergen Trail consists of the following contests:
Each team in the 500K TEAM contest may consist of 2 or 3 persons.
The team must stay together all the way from start to finish, within a distance of 50 meters.
In the following, a participant means either a runner taking part in one of the individual contests or in the team contest.
The contests have two classes, Women and Men.
The teams (in 500K TEAM) consisting only of women participate in the women's class; all other teams participate in the men's class.
Each contest follows a given main route. Under difficult weather conditions the participant may in certain parts be directed to an alternative route. The participant shall only use an alternative route if this has been instructed by the organizer.
As a standard rule the participants are ranked on the final results list. However, the organizer may decide differently if the use of alternative routes makes it difficult to rank the participants.
To get an approved result in an individual contest, the runner must complete within the time limit.
To get an approved result in the team contest, the team must, with at least two members, complete within the time limit. If the team at some point is reduced to only one member, it is taken out of the competition.
Time barriers are given at the service stations. Individual runners and teams that have not left the service station by the specified time are taken out of the competition.
If a team is reduced to only one member it is taken out of the contest. The remaining runner will then have the option to convert to the 500K (individual) contest, given that the time barriers have not been exceeded at the time of conversion. If the runner reaches the finish before the time limit, he will get status as a finisher, but appear without ranking at the bottom of the results list.
The participant has to carry obligatory equipment in accordance with a detailed list, which is published on the website. The obligatory equipment has to be carried by the participant along the whole route from start to finish.
Poles may be put in the drop-bag given they fit in their entirety inside a closed bag. Placing poles in the drop-bag is at own risk, the organizer does not take responsibility for any damage to poles during transport.
The race is based on the principle of self-support, which means that each participant must carry all food, drink, and equipment needed along the route. It is however allowed for the participant, in person, to buy food and drink from shops and gas stations along the route.
To receive support from people not in the organizer’s staff is not allowed at any location along the route.
To create or use depots along the route is not allowed.
Pacing (to be accompanied by someone not participating in the race) is not allowed.
The organizer will hand out two drop-bags to each participant:
Only the bags given by the organizer can be used as drop-bags.
Each team and each individual participant are carrying a GPS tracker, provided by the organizer. The tracker is handed out before the start and is then ready for use. The tracker is attached to the outside of the backpack, with a clear view of the sky.
To attach the tracker to the backpack one must use the means of attachment provided by the organizer. It is not allowed to use means of attachment that require tools to be removed (e.g., strips), as this may cause damage to the tracker.
Participants must not operate the trackers themselves unless the organizer gives notice of this.
If the participant happens to lose a tracker, then the participant will be billed for the organizer's cost of obtaining a new one.
Runners who want a bed will be allocated a time slot of maximum 4 hours during which the bed can be used. In case of high demand, some waiting must be expected.
The race is conducted without compulsory breaks— it is mainly up to the participant to decide when to take a break, but some restrictions apply concerning where to stay during the break.
Outdoors, the participant can take a break anywhere along the route. Indoors, one can only take a break:
In tourist cabins and other accommodation, shops, gas stations etc., located along the route or at a short distance from the route. These places must be open to the public.
In other places near the route that provide shelter, when these are accessible to everyone, e.g. stone shelters, emergency shelters, lavvoers, gapahuks.
To take breaks in private houses, cabins, cars, mobile homes, etc. is not allowed and may lead to disqualification of the participant.
If a participant takes a break in other locations than the service stations, all eventual costs must be covered by the participant.
In some situations, the organizer may instruct a participant to take a break, e.g.,
To quit the race is only allowed at the service stations.
The following applies to participants who quit or are taken out of the race:
