About
Ultra-Trail Kosciuszko by UTMB runs each November in the Snowy Mountains of New South Wales. The KosciMiler leaves Banjo Patterson Park in Jindabyne at 3 a.m.; the Kosci100 leaves Perisher Ski Resort the same morning. Both climb to the summit of Mt Kosciuszko, the highest peak in Australia, and both finish at Friday Flat in Thredbo, so the courses are point to point rather than loops.
It is a UTMB World Series event, so a finish earns Running Stones toward the Chamonix lottery, and the weekend adds a 50 km and a 32 km race on the Thursday. The fields are large for a late-season race: 1,073 runners started the Kosci100 in 2025 and 893 finished, against 340 starters and 221 finishers on the miler.
Course
Point to point over the summit of Mt Kosciuszko, finishing at Friday Flat in Thredbo. The KosciMiler covers 161 km with 5,131 m of climbing from Banjo Patterson Park in Jindabyne, on a 36-hour limit; the Kosci100 covers 106 km with 3,260 m from Perisher Ski Resort, on 28 hours. Late November is southern-hemisphere spring, and snow still lies on the high sections in some years.
How to register
Entry is first come, first served. Runners holding a valid UTMB Index get a 48-hour priority window before general entries open, and the races sell out. The KosciMiler asks for a documented 50 km or longer finish from the two years before the race; the Kosci100 sets no prerequisite.
