Experience the magic of winter endurance at the Diablerets Trail Blanc, returning to the snow-covered peaks of Switzerland on February 21, 2026. Nestled in the majestic massif of Les Diablerets, this event is a highlight of the "Diablerets 3D" weekend, blending a festive village atmosphere with high-altitude athletic challenge. Runners will navigate north-facing slopes and enchanted forests, starting and finishing in the heart of the village at 1,200 meters. Whether you are racing under the moonlight or the brilliant alpine sun, the Trail Blanc offers an "enchanting setting" that pits human determination against the pristine, frozen wilderness of the Ormonts Valley.
The 2026 edition offers a technical spectrum of races tailored for every level of winter runner. The flagship La Tréchadèze (20 km) challenges athletes with 900m of elevation gain, following a historic route along the River Grande Eau named after a legendary 1798 battle site. For those new to the snow, the L'Ormonanche (10 km, +450m) provides a perfect initiation, traversing the banks of the river and the dramatic Cirque de Creux de Cham. True vertical enthusiasts can test their lungs in La Verticale, a grueling Saturday evening sprint covering 3.5 km with 558m of ascent, while the Mini-Diablotins race ensures that young trail blazers under 12 can join the fun on a dedicated 1 km loop.
Safety and preparation are paramount for this high-altitude journey, with registration managed through the official Diablerets 3D portal. Participants must carry mandatory safety gear, including a survival blanket, whistle, and mobile phone, to navigate the unpredictable mountain environment. Beyond the finish line, the event is famous for its warmth and camaraderie, featuring a traditional post-race dinner and live music that echoes through the valley. Secure your spot in this winter wonderland to discover why Les Diablerets remains a premier destination for those who seek to run where the mountains meet the sky.
