This is where the party starts. For those just getting into trail running, who’ve ticked off a road half and are looking for something to get excited about – the Kosci30 is made for you.

We’ve hand-picked the best trails, the best elements of the alpine ultra experience and whittled it down into 30 of the best kilometres ever.

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:

  • In order to fit in the best trails, the Kosci27 will become the Kosci30 – a 30km race with significantly less elevation gain than 2023.
  • Overall cutoff time for all races will remain the same, and cutoff pace for all races will remain the same as 2023.
  • The number of Aid Stations on course will remain similar for all distances as 2023.
  • The finish line for all distances will remain at Friday Flat in Thredbo.
  • The start lines for all distances will be shifting in 2024 to new locations, all within the Snowy Mountains area.
  • We will be running shuttle buses for all distances 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 or 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!



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


The Kosci30 has checkpoints along its route, with differing levels of service and supplies. The Kosci30 checkpoints offer you the opportunity to refuel, rehydrate and prepare for the next leg of your journey!

A Finish Line Drop Bag service will be available which allows you to have your own personal supplies (change of clothes, shoes, shorts, post race nutrition, etc.) at the finish line.
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.
Read Mandatory Gear rules


The Kosci30 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.
