Course Overview

All of our courses, from the KosciMiler to the Kosci27, have been designed by trail runners, for trail runners. UTA founder Tom Landon-Smith heads up the course team, and they’ve put together what can only be described as trail running bliss. Super runnable trails, stunning scenery, achievable elevation gain and unrivalled support crew access, make this Ultra-Trail running at its best.

All four races start in Thredbo, with the finish line and trail village located in Bullocks Flat, a short 20-minute drive from Jindabyne.

For those new to the sport of trail running, the Kosci27 is made for you. Non-technical trails have been linked together to take in some of the best parts of the longer courses, sure to bring a smile to your dial that your road running escapades could never emulate.

The Kosci50 is a perfect step up from a marathon and comes with its own bragging rights of being an ultra-distance race. Don’t let that deter you though, as it’s one of the most achievable ultra’s out there, with smooth flowy trails, a good mixture of elevation, stunning scenery and bucket loads of support.


For the seasoned trail runner and endurance athlete – the Kosci100 is one you’re gonna want to add to your bucket list. Bringing the alpine ultra experience to Australia, the Kosci100 takes you through alpine meadows and snow gum bush, as well as to the summit of Australia’s highest peak – Mt Kosciuszko. It doesn’t stop there, as you dart between each mountain village along the way before a final stretch up the Thredbo Valley Trail. Don’t be fooled by the word alpine, courses aren’t overly steep and are super runnable – great for first time triple-digit runners and experienced ultra-athletes alike.

For the ultimate test of mind and body, the KosciMiler brings a premier 100 Mile run to the shores of Australia. From the summit of Mt Kosciuszko to the waters of Lake Jindabyne, with endless trail bliss, alpine scenery and ski villages in between – the KosciMiler journey is one you’ll never forget.
