|UTMB World Series||
The Kosci100 is a UTMB Worlds Series 100K Event. Finishers of Kosci100 will receive 3 running stones.
We’ve left no stone unturned when designing the Kosci100 course – made with both the 100km first timer and ultra-endurance junkie in mind.
Following much of the same route as the KosciMiler, the course kicks off in the alpine village of Thredbo, before taking in highlights like the mountainside Thredbo trails, alpine plateau, Kosciuszko summit and ski village checkpoints.
From there runners will head below the tree line into snow gum forests, with trails twisting and turning beneath the trees, funneling down to Sawpit Creek before shooting up the Thredbo Valley Trail to the finish line at Thredbo.
Don’t let the sign of mountains fool you – with only 3000m of climbing over the 100km, the Kosci100 is on the much more runnable side, with wide trails and smooth rolling hills.
*Maps subject to change, and may change for reasons outside of the Race Orgaisers control. Select the Time Charts tabs to view the cut-off times for leaving the relevant checkpoint. Time Charts show estimated fastest and slowest times for each race leg and should be used as a guide only. Where the slowest times are greater than cut-off time, the cut-off time will supersede the slowest expected estimates. If you miss the cut-off then you must follow the directions of officials. Please note that in bad weather conditions, cut-offs may need to be brought forward during the event.
KEY INFO FOR KOSCI100 RUNNERS
All the information you need to know before starting an extraordinary adventure.
The Kosci100 has 8 checkpoints along its route, with differing levels of service, support crew access and supplies. The Kosci100 checkpoints offer you the opportunity to refuel, rehydrate, see your support crew and prepare for the next leg of your journey!
Read more about checkpoints
A drop bag service will be available which allows you to have your own personal supplies (gels, food, change of socks, shoes, shorts, lubricant, etc.) available at certain check points or at the finish. Please see the time charts above for information on which checkpoints have drop bags.
Read the rules on drop bags
Every runner at Kosci will have to carry mandatory gear. The mandatory gear list contains what we believe is the absolute minimum to keep you safe during the event and in the Snowy Mountain’s unpredictable weather systems. For Kosci100 runners, your gear will need to be checked pre-race.
Read Mandatory Gear rules
TRAINING ON COURSE
The Kosci100 course is publically accessible throughout the year , offering the opportunity to train on course prior to raceday. However note that many sections are covered in snow in the colder months.
Please take care and give way to members of the general public when training on course.

We love support crews almost as much as our runners at Ultra-Trail Kosciuszko by UTMB – you are always the most colourful (and loudest!) and a huge part of the magical atmosphere of the whole weekend.
You also have the very important job of getting your runners to the finish line.
First job for support crew is to read the support crew section in the Runner Guide, available one month before the event. It contains important information you will need to know for the event.
To keep the event manageable as well as fair and safe for all athletes, and to make sure support crews do not get lost, there is some information that support crews need to know.
- Support crews are allowed to assist runners at all Checkpoints except for CP6 at Trout Hatchery.
- Support crews can access Eagles Nest Checkpoint via the Kosciuszko Express Chairlift. You can book lift passes here.
- Support crews may only assist their runners within 200m either side of the checkpoints. Support Crews cannot run alongside their runners at any point on the course outside of the checkpoints.
- Pacers are not allowed for athletes in the 100k distance.
