COURSE DESCRIPTION

Made with both the 100km first timer and ultra-endurance junkie in mind, the Kosci100 course is about as fun as 100km running can get.

We’ve got some exciting new developments planned for the 2024 event, thanks to some newly finished trails in the area that we’re excited to take runners on, as well as taking learnings and listening to feedback from the 2023 event on what you liked and what you didn’t.

We had hoped to be in a place to be able to share these in advance of entries opening for 2024, however as is the way with events, we have to make sure we tick all the boxes before we release courses to the public, and we still have a few more boxes to tick before we can do that.

We want to be as open as we can about what you can expect for the 2024 event ahead of entries opening, so here’s what we can say for now:

  • Kosci100 course will be of a similar nature to 2023 in terms of distance, within 8% of the category distance
  • Total elevation gain for the Kosci100 will increase by between 5-10% from 2023
  • Overall cutoff time will remain the same, and cutoff pace will remain the same as 2023.
  • The new course will see a significant decrease in the amount of sealed surface used.
  • The number of Aid Stations on course will remain similar for all distances as 2023.
  • The number of support crew access points for the Kosci100 will remain similar to 2023.
  • The finish line for all distances will remain at Friday Flat in Thredbo.
  • The start line will be shifting in 2024 to a new location within the Snowy Mountains area.
  • We will be running shuttle buses to all start lines from Thredbo and Jindabyne – these will be available to book through your MyEvents account. All start lines will have plenty of parking for supporters.
  • The best places to book accommodation are Thredbo or Jindabyne.

Overall – the nature of vibe of the courses we’re trying to create will be the same – amazing scenery, happy trails, and ultimately a challenging but achievable event.

We are working closely with stakeholders to lock these in, and we hope to communicate these with you as soon as possible to help with your preparation and planning. Stay tuned for updates and we’ll share them with you as soon as we can!

COURSE DESCRIPTION

KEY INFO FOR KOSCI100 RUNNERS

All the information you need to know before starting an extraordinary adventure.

CHECKPOINTS

The Kosci100 has 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

DROP BAGS

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

MANDATORY GEAR

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.

SUPPORT CREW

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.
