Ultra-Trail Kosciuszko by UTMB: Route, live tracking and how to enter

Ultra-Trail Kosciuszko by UTMB is a UTMB World Series event in Australia, with races ranging in distance, technical elements and elevation.

The race takes place in the Snowy Mountains, home to Mount Kosciuszko, the highest peak in mainland Australia, after which the race is named. Situated on the border between Victoria and New South Wales, this race is perfect for anyone wanting to discover the natural beauty of the Australian interior.

Kosciuszko by UTMB features four different races, with a 27km beginner race, in addition to the usual 50k, 100k and 100 mile categories at UTMB World Series events, with all distances offering runners the chance to collect the running stones they need to have a chance to compete at next year’s UTMB Mont Blanc.

Ultra-Trail Kosciuszko by UTMB Route

[Update: Due to unexpected and ongoing snowfall, the routes have been modified – full details here]

The Kosci Miler is the crown jewel of the event, with the 164km route encompassing 5185m of elevation gain as the athletes race from the Friday Flat in Thredbo to the finishing line at Bullocks Flat at the Ski Tube Terminal.

In the Kosci Miler, the athletes will run from the start in Thredbo up into the mountains, before crossing the alpine plateau to the highest peak in Australia, Mt Kosciuszko.

From the summit, they’ll run down the trails of Perisher Valley to Lake Jindabyne. After a boat crossing of the lake, the competitors will turn on their heels back up the Thredbo Valley trail to the finish.

The Kosci 100 is the second race starting from Thredbo on the Friday, with athletes racing over the 100km distance that includes a total elevation gain of 3478m. Once again, the finishing line will be at Bullocks Flat at the Ski Tube Terminal.

The course follows the same route as the Kosci Miler for the first 50km, up to the summit of Mt Kosciuszko, before the Kosci 100 racers run down to Sawpit Creek before heading back up the Thredbo Valley trail to the finish.

The Kosci 50, starting and finishing in the same place as the Kosci Miler and Kosci 100, is the first race on the Thursday and will see athletes tackle 1626m of elevation gain over 50km.

The route follows the Thredbo river down to Dead Man’s Gap, before ascending to the highest point on the course, the Eagles Nest. From here, the rest of the way is predominantly downhill, as the athletes reunite with the Thredbo river all the way down to the finish at Bullocks Flat.

Finally, the Kosci 27, again starting at Friday Flat in Thredbo and finishing at Bullocks Flat, will see the competitors take on 870m of climbing over the 27km course. The course on the Kosci 27 reaches its highest point out at the Eagles Nest, before picking up the Thredbo Valley trail and running alongside the Thredbo river to the finish at Bullocks Flat.
