The NAC Trail Run 2026 takes place on 6 September 2026, and it’s one of the most anticipated dates on Niseko’s autumn outdoor calendar. Three distances, including 5km, 10km, and 30km, mean this isn’t an event reserved for elite athletes with something to prove. It’s designed for the whole spectrum: the first-timer who wants a taste of trail running, the intermediate runner chasing a proper challenge, and the experienced mountain athlete ready to go deep into Niseko’s landscape.
