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 Kosci27 is made for you.

We’ve hand-picked the best trails, the best elements of the alpine ultra experience and whittled it down into 27 of the best kilometres ever.

Starting in Thredbo and ascending towards the Eagles Nest, runners will pick up flow trails on their way back down as chairlifts swing above them and they scoot between ski runs. They’ll then pick up the Thredbo Valley Trail and the sounds of trickling water as they follow the Thredbo River down to their finish line at Bullocks Flat.

The hardest part? Resisting the urge to step up to the Kosci50 next year…

  • Toilets

Please note we are a cup-less event. In an effort to cut down on waste, we will have no drinking cups at checkpoints. You will need to carry a cup or hydration pack with you. Limited stock of cups and hydrations packs will be available for sale at the event expo, but we encourage you to purchase one in advance and use it in your training.

Signs will be placed 200 metres before each checkpoint and exit signs will indicate the distance to the next checkpoint.

First Aid will be available at each checkpoint and the finish. There will also be roving first aid crews on the course.

If you are using a support crew, you must also read the Support Crew section.

Drop Bags

A drop bag service will be available which allows you to have your own personal supplies returned from the start line to the finish.

Your bag needs be closable and soft and a reasonable size. In line with our commitment to sustainability please don’t use plastic bags or plastic boxes – these will not be accepted. One drop bag per runner is allowed.

Finish line drop bags can be left in the designated area near the start line at Thredbo on Friday morning.

Drop bags will be returned to the drop bag marquee at the Kosci Trail Village. Collect by showing your race number. Any drop bags not collected by 6pm on the Saturday will be disposed of.

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 only allowed to assist runners at certain checkpoints (full details provided prior to the event)
  • Pacers are not allowed for Kosci27 runners.
  • Support crews cannot run alongside their runners at any point on the course outside of the aid stations.
