TALK

The non-profit association “Trail Valais,” based in Crans-Montana, launched the Wildstrubel by UTMB in Crans-Montana in 2022.
Its mission is to promote trail running in Valais.

The management committee

What I enjoy most about this role:
The atmosphere within the local committee is friendly and cordial. Everyone is passionate about event planning and brings their own expertise to the table. The tasks vary throughout the year, ranging from booking speakers and accommodations to handling permit applications, developing the safety concept, securing sponsorships, managing marketing, and communicating with the runners—among many others. It’s a truly enriching experience. Finally, the event day is the cherry on top—it’s the culmination of all our hard work. The emotions of the runners at the finish line are our greatest reward.

What I love about the Wildstrubel by UTMB:
The courses are incredibly diverse and wild. I also appreciate the connections with the various team leaders and volunteers who come from different linguistic regions.

Ryan Baumann 

What I love most about this mission:
The connection with the volunteers and seeing all these people generously giving their time for our runners. We have an amazing atmosphere within the organization and, of course, the best volunteers in the world!

What I love about the Wildstrubel by UTMB:
The scenery, the scenery, and the scenery! On this wild course, you come across cows, horses, and goats, but also marmots and chamois. The Valais side offers views that are raw and rugged—sometimes almost hostile—while the Bernese side is gentler, with its pastures and greenery. Add in rivers and lakes, and you've got everything you need to feast your eyes... and test your legs!

Volunteer Manager, Runner Awards, and Gifts Coordinator

Magali Reiser 

What I enjoy most about this role:
It's seeing part of the local population—especially the children of the region—come together and run as a group. There’s nothing more motivating than watching local youth push themselves, share that energy, and embrace the joy of movement. I also deeply value the inclusion of the para sport race, which gives everyone—regardless of their abilities—the chance to experience this incredible sporting adventure and feel the emotion of the race.

What I love about the Wildstrubel by UTMB:
It truly feels like a “home race.” I work just 100 meters from the finish line, and it’s a real pleasure to feel the thrill of the event through the experiences of the participants. The courses are stunning and take place on my usual training grounds. I’m especially proud to be on the organizational side of Wildstrubel by UTMB, as I’m usually the one wearing a bib and running!

Coordinator for Wild Kids, Para Sports, and Wild NextGen

Bastien Siggen

What I love most about this mission:
Above all, it’s the human connections and interactions that are created through event work. It’s a living project that evolves, grows richer, and constantly pushes us to learn and adapt. We pour in energy, ideas, hours… but above all, a lot of passion. Working an entire year for just one weekend is a real challenge — it’s a bit like carrying a “baby” together for months, and then seeing it born beautifully on the big day, despite all the unexpected twists. The adrenaline rush on that day is truly unmatched...

What I love about the Wildstrubel by UTMB:
It’s the opportunity to showcase our landscapes to runners and spectators. The courses are absolutely stunning and incredibly varied. The organizing team is made up of passionate people who are committed to creating a local and authentic atmosphere, and I’m proud to highlight our region, our products, and our traditions.
At the finish line, you can feel each runner’s achievement, their emotion, and their personal triumph. But I don’t stay there too long (no time, unfortunately — and definitely not enough tissues).

Coordinator for Entertainment, Food Services, Refreshments, and Awards Ceremony

Laurence Meyer 

What I enjoy most about this role:
At the Race Operations Center, I’m at the very heart of the event. I experience the race as an organizer—closely following both the frontrunners and the anonymous participants—while keeping a watchful eye on all the checkpoints. By the end, we’re just as exhausted as the trail runners!

What I love about the Wildstrubel by UTMB:
What I enjoy the most is the entire section of the course between the Rawyl Pass and Varenalp—for two reasons. First, it was my playground back in the 1980s. Trail running didn’t exist yet, but I was already running all over those paths. Second, it’s the history of the region—a rural area shaped by irrigation channels (bisses) and tourism. I often reflect on how my ancestors lived through these transitions.

Pierre-Michel Oggier

What I love most about this mission:
It’s the opportunity to innovate, rethink, and improve the finish area every year. Nothing is ever set in stone — we’re always looking to do better, to fine-tune the details, and to create an atmosphere that’s even more welcoming, festive, and smooth-running. It requires thought, imagination, and a real search for practical solutions — but that’s exactly the kind of challenge that motivates me.
It’s truly a team effort, where everyone brings their ideas, experience, and energy. My goal is for the main finish area to be much more than a logistical space: a place full of life, warmth, and celebration — where runners can release the pressure, families can reconnect, and spectators can soak up the atmosphere.

What I love about the Wildstrubel by UTMB:
First and foremost, it’s the incredible energy at the finish line — the faces of the runners as they cross it, filled with emotion, effort, and pride… Those are powerful moments that capture everything we’ve been working toward for months.
But it’s also the fact that, thanks to this race, thousands of people discover a region I know inside out and love deeply — these mountains where I work, hike, and feel truly passionate. It’s a joy to see runners immerse themselves in the landscape and the atmosphere, and leave with unforgettable memories.

Manager of Ycoor Finish Area, Exhibitor Village, Signage, and Equipment

Michael Meyer 

What I enjoy most about this role:
This position gives me a global view of the event and allows me to interact with runners, volunteers, and various service providers.

What I love about the Wildstrubel by UTMB:
The team spirit driven by a local committee made up of motivated people who love their region and the world of trail running.
