Race bibs can be collected from The Sporting Park Engelberg – Engelbergerstrasse 11, 6390 Engelberg, on Friday the 22nd August 10:00 – 16:00.

Limited bib collection will also be available on the morning of the race, but we strongly recommend that 100km participants collect their bibs in advance to avoid last-minute stress and potential delays

Yes, participants in the 56km and 100km races will be equipped with a GPS tracking module for safety and live tracking purposes. These modules will be distributed when you collect your Race Bib. They will be taped onto your pack which you will also have to present to prove you have the Mandatory required Kit.

Please note: GPS trackers must be returned immediately after crossing the Finish Line. This ensures accurate tracking and helps us manage equipment efficiently for future events.

While the general regulations in Switzerland do not mandate a medical certificate we strongly reccomend that you obtain a certificate to confirm your capacity to participate in an endurance Trail Running event.

Frutt Mountain Resort (100km race): A scenic and accessible spot that’s perfect for friends and family to catch runners during the longer distance.

Engelberg Sporting Park (100km, race): This central location is not only a lively support point for all three races but also serves as a Base de Vie (life base) for the 100km event—making it ideal for extended support and atmosphere.

Wolfenschiessen & Horbis (100km and 50km races): A beautiful alpine location with great access for supporters and a key moment in the race where encouragement goes a long way.

100K & 50K, 25K race – Fürenalp

We encourage all spectators to respect the natural environment, follow signage and local guidance, and cheer responsibly—your support means the world to the runners!

Cut-off times are in place for the safety of all participants and will be strictly enforced at designated aid stations and safety checkpoints along the course. Please ensure you are aware of the time limits for your race:

100K – Maximum time: 24 hours

50K – Maximum time: 14 hours

25K – Maximum time: 8 hours

Staying ahead of these cut-offs is essential for your safety and to remain an official finisher. Plan your pacing accordingly!

The use of headphones is discouraged. If you choose to wear headphones, please ensure that you can hear all announcements and remain aware of your surroundings, including other participants, and that the volume is low enough so that the sound is not audible to other runners. Please take any or all considerations seriously by race officials regarding course safety.

Your race bib must be worn visibly on your chest at all times during the race. Please do not fold, wrinkle, or modify the bib, and make sure it is not covered by a jacket, running belt, hydration pack, or any other item.

Proper bib placement is essential for identification, safety, and accurate timing—help us keep everything running smoothly!

Your safety is our top priority. In case of an emergency, the designated emergency contact number will be:

Printed on your race bib

Clearly displayed in the Event Village

Communicated during the official race briefing

A fully equipped safety and medical team will be present throughout the event—both in the Event Village and strategically positioned along the course—to respond quickly to any situation.

The event takes place in classic Alpine terrain, so expect a mix of steep climbs, rocky trails, forested sections, and open mountain landscapes. In late August, the Alps typically enjoy warm temperatures, with average daytime highs ranging from 18°C to 25°C (64°F to 77°F). However, conditions can change quickly in the mountains, with occasional rain or cooler winds at higher altitudes.

One important consideration: in recent years, we’ve occasionally experienced periods of excessive heat even this early in the summer. Please come prepared with adequate hydration, sun protection (hat, sunscreen, sunglasses), and lightweight, breathable clothing. Staying informed and ready for varying conditions is key to enjoying a safe and successful event.

To ensure fairness and safety for all participants, race rules and regulations are actively monitored throughout the event. Here’s how:

Volunteers and safety personnel are positioned at regular intervals along the course, with additional roaming race agents observing and supporting runners.

These teams are there to ensure compliance with race regulations, safety advice, and environmental guidelines.

Mandatory equipment checks will also take place in the Event Village before the race starts, so please arrive prepared and allow time for this process.

We appreciate your cooperation in helping us deliver a safe, fair, and enjoyable race experience for everyone.

Yes – there is a mandatory pre-race briefing held 30 minutes before the start of each race, just next to the start line.

This briefing includes important safety updates, course information, and last-minute instructions, so we kindly ask that all participants attend to ensure a smooth and informed race experience.

Don’t miss it—it’s the best way to start your race fully prepared!

All race results and timing statistics are recorded using chip timing and will be published on the official event homepage shortly after the race:
👉 https://www.runthroughtrails.com/engelberg/

Keep an eye on the site post-race to check your time, rankings, and share your performance with friends and family!

Yes, the event takes in an area of stunning natural beauty, which means it is part of a network of the most valuable natural habitats in Europe.

Preserving the integrity of this unique environment is a shared responsibility.

We kindly ask all participants to help reduce human impact by keeping noise to a minimum, especially in forested or wildlife-sensitive areas, and by staying on marked trails to avoid damaging fragile vegetation. Please avoid littering—carry out everything you bring in—and respect local wildlife by not disturbing animals or nesting areas.

Your awareness and respect for the environment help ensure that events like this can continue to take place in such stunning natural settings. Let’s all do our part to protect it.

For help with accommodation bookings and local travel options, we highly recommend contacting the Engelberg Tourist Office. Their team is friendly, knowledgeable, and ready to assist you in finding the best stay for your race weekend.
