2. Principles for Organizers

2.1 Minimal impact on nature and environment

• We choose routes that are ecologically responsible and officially permitted.
• Vulnerable zones are avoided or temporarily closed if necessary.
• Start and finish areas are set up in such a way that disturbance to fauna and flora is minimal.
• Noise and light pollution are limited to the necessary minimum.

• Single-use plastic is avoided as much as possible.
• Reusable cups, water bladders, or soft flasks are mandatory or strongly recommended.
• Markings are made reusable and completely removed after the event.
• The organization works, where possible, with recycled or biodegradable materials.

• All aid stations are equipped with clearly marked waste zones.
• Crew and volunteers actively monitor the course for abandoned waste.
• After the race, the entire course is cleaned up and left in its original condition.

• Participants are encouraged to use carpooling, bicycles, public transport, or shuttles.
• Parking space is kept limited to reduce pressure on nature.

• The organization communicates timely with residents and municipalities.
• Disturbance is limited and accessibility to homes is guaranteed.

3. Principles for Participants

3.1 Respect for nature and environment

• Runners follow the official course at all times — no shortcuts, no off-trail running.
• Picking, damaging, or disturbing plants, trees, or structures is prohibited.
• Animals must be left alone; feeding, approaching, or disturbing them is not allowed.

• Leaving waste on the course leads to immediate disqualification.
• Waste (wrappers, gels, drink pouches) must be kept until an official waste zone.
• Participants ensure that personal equipment or tape does not come loose or remain on the course.

• Reusable cups or flasks are mandatory where possible.
• The use of music or sound must not disturb others and may not disrupt wildlife.

• Safety comes first: in emergency situations, every participant helps others where possible.
• Behavior that is disruptive, dangerous, or unsportsmanlike is not tolerated.

• During nighttime hours, disturbance to wildlife is particularly sensitive; participants therefore move quietly and respectfully through the terrain.
• The use of headlamps is limited to what is strictly necessary for safety. Bright flashing or high-powered lamps are not allowed, except in an emergency.
• Noise pollution (voices, music, phone calls, poles clanging together…) must be kept to a minimum.
• Grouping is allowed, but loud groups are not.
• Leaving the marked trail is strictly prohibited, as this creates an increased risk of disturbance or damage at night.
• Participants are encouraged to give space to animals that appear unexpectedly and adjust their pace if necessary.

4. Measures & Control

4.1 Enforcement

• Crew members and marshals monitor compliance with this charter.
• Violations may lead to warnings, time penalties, or disqualification.

• The organization documents the state of nature before and after the event.
• Feedback from local partners and nature management is incorporated into future editions.

• After the event, the charter is evaluated and tightened where necessary.
• Participants, partners, and volunteers can suggest improvements.

5. Final statement

By participating in this event, the runner acknowledges that nature conservation and respect are a shared responsibility. Together we care for the landscape that gives us the opportunity to experience this unique challenge.

Together we run with respect — for each other, for nature, and for the future.
