About This Race

The 163K represents the ultimate test at MUT by UTMB, demanding exceptional endurance and mental fortitude as runners traverse the full spectrum of the Outeniqua Mountains' challenging terrain over what will likely be a day-and-night journey. This distance requires seasoned ultra-distance runners who can manage complex pacing strategies across technical single track, sustained climbs, and potentially variable weather conditions that come with extended time on the mountain. The extended duration means experiencing the fynbos and forest trails through different lighting and atmospheric conditions, creating a deeply immersive mountain experience that tests both physical preparation and navigation skills in low-light conditions.
