About the Event

Challenge the high Alps in the heart of Switzerland's largest nature park at the Swiss Irontrail on June 27-28, 2026. This unique trail running experience in the Parc Ela takes you through a breathtaking world of steep peaks, vast landscapes, and glacial lakes, with routes ranging from the formidable T78 to accessible 20km courses. Set in the pristine Val Surses, the event demands respect for mountain conditions, where temperatures can plummet and snow is possible, making proper gear and acclimatization part of the authentic adventure. The Swiss Irontrail is not just a race; it's a pure, high-altitude journey that pushes your limits amidst some of the most raw and powerful scenery the Alps have to offer.
