From alpine meadows to snow gum forests, golden pastures to lakeside trails, crystal‑clear creeks and the ultimate mountain summit — the KosciMiler course delivers the full Ultra‑Trail experience.

Starting in the heart of Jindabyne to the roar of the crowds, runners begin their journey toward the highest peak on mainland Australia.

Tracing the edge of Lake Jindabyne, the course heads into the hills and onto the Thredbo Valley Trail before climbing to the alpine plateau.

With Perisher, Charlotte Pass, Mt Kosciuszko summit, Guthega and Smiggin Holes on the route, the KosciMiler captures the very best of Australia’s alpine wonderland.

Runners then descend into the Thredbo Valley for their final stretch, finishing 100 miles later with a lap up and over the Thredbo Ski Area, crossing the line at Friday Flat.

It’s 100 of the most beautiful, scenic and flowy miles you’ll ever run - the ultimate ultra‑trail experience.
