Race regulation:

Art. 1: Winter running in the middle of nature, mostly using hiking routes and crossing the Jurassien Vaudois Regional Park. The race takes place at night and requires an individual lighting system.

Art. 2: Because we love nature, let's respect it. It is imperative to follow the paths as they are marked, without cutting. In fact, cutting a trail causes significant disturbance of wildlife and irreversible erosion of the site, thus degrading it irreparably. Do not throw away bar wrappers or handkerchiefs. A few grams in your pockets will not delay you and will allow everyone to take full advantage of this superb region and to be able to return there. Each participant undertakes to respect the Eco Trail Charter appended to these race regulations. Any competitor found in violation will be immediately disqualified.

Art. 3: These races are open to anyone, man or woman, born in 2003 or before, (senior to veteran categories), licensed or not. Each participant agrees to have sufficient training and to be in a state of health allowing him to participate in the event for which he is registered. Participation in the nocturne des loups entails the unreserved acceptance of these rules and the ethics of the race.

Art. 4: With our partner MSO Chrono, you have the option of taking out cancellation insurance when you register. This is the only way to be entitled to request a refund.

Art. 5: No glass or cup will be provided, hence the obligation of a personal cup for the duration of the race.

Art. 6: No cash prize is distributed. A classification for each category is established as well as a scratch classification. The first 3 men and the first 3 women of the general classification, as well as the first 3 of each category will be rewarded.

Art. 7: Competitors refusing to comply with these rules will be eliminated, in particular for:

  • No bib

  • Bib falsification

  • Delay at the start of the competition

  • No check-in at checkpoints

  • Pollution or degradation of the sites crossed (cutting the paths, littering)

  • Refusal to be examined by health personnel

Anyone who does not have an individual lighting system will not be allowed to start or will be disqualified

Art. 8: Each competitor expressly authorizes the organizer or beneficiary to use his image, his voice and sporting performance for any direct exploitation or in derivative form of the event and this, on any medium throughout the world by all known and unknown to date and this for an unlimited period.
