102km of alpine bliss — summit to valley through the Snowy Mountains
The Kosci100 delivers 102km of highly runnable alpine trails through the Snowy Mountains, including a summit of Mt Kosciuszko. Starting at Perisher Ski Resort, runners traverse the Snowies Alpine Walk along the ridgeline to Charlotte Pass, ascend to the summit, then wind out to Guthega and back through Smiggin Holes before descending to Bullocks Flat and finishing at Friday Flat in Thredbo. An excellent high-finish-rate course with outstanding trail quality and crew access throughout.
