Face the ultimate winter challenge at the CRUX Winter Ultra Run on Saturday, March 14, 2026, where the stark beauty of a frozen landscape meets pure endurance. Now in its 16th edition, this formidable event offers two brutal distances designed to test your physical and mental fortitude: the demanding CRUX Contessa (28km / 1,500m ascent) and the epic CRUX Count (56km / 2,300m ascent). It's a raw, unflinching test where runners must be self-sufficient, battling not just the distance but the harsh alpine elements.
This is more than a race; it's a pilgrimage for seasoned trail and ultra runners seeking authentic adventure beyond fair-weather conditions. The course weaves through silent, snow-draped forests and over exposed ridges, demanding respect and meticulous preparation. Embrace the stark solitude and intense camaraderie that only a true winter ultra can provide, where every hard-earned kilometer is a triumph against the cold. Toeing the start line means committing to an unforgettable journey where finishing is the sole, monumental victory.
