UTMB Qualifying 2025 ws50KM
The UTA50 is a UTMB World Series 50K Event. Finishers of UTA50 will receive 2 running stones.


The UTA50 course traces the second half of the UTA100 course, and does not lack for the beauty or stunning landscapes of its longer counterpart.

You’ll start at Scenic World in Katoomba and be heading along the cliff tops, checking out the breath-taking views of Mt Solitary and the escarpments before you know it.

The spectacular Wentworth Falls is the next highlight after around 25km, before cruising down the epic Kedumba Pass.

The only way is up from there, culminating with the finish line back at Scenic World!

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


The UTA50 has 3 checkpoints along its route, with differing levels of service and supplies. The UTA50 checkpoints offer you the opportunity to refuel, rehydrate, see your spectators and prepare for the next leg of your journey!

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 the finish.
Read the rules on drop bags


Every runner at UTA 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 Blue Mountain’s unpredictable weather systems.
Read Mandatory Gear rules


To help congestion on the course and ensure an enjoyable and safe race for everyone, we have a tried-and-tested start group process to match-up runners of similar abilities. Find out more about the start group request process, seeding options and start group times.

A large portion of the UTA courses are publically accessible throughout the year, offering the opportunity to train on course prior to raceday. Please take care and give way to members of the general public when training on course. Some sections of the course are on private land, so please read about these before heading out.

We love support crews almost as much as our runners at Ultra-Trail Australia 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 can only assit their runners within the bounds of the Checkpoint.
  • Support crews are only allowed to assist runners at Checkpoints 1 (Fairmont) and 2 (Queen Vic Hospital) (these checkpoints can be accessed with a standard 2-wheel drive)
  • Support crews cannot drive, ride or walk on any section of course to service their runner.
  • Pacers are not allowed for athletes in any distance.
  • Support crews cannot run alongside their runners at any point on the course outside of the aid stations.
