Narrow Neck, Ironpot Ridge, Leura Forest, Wentworth Falls, Kedumba Pass, Giant Steps – names that have that become trail running legend as part of the iconic UTA100 course.

It’s the race that every trail runner in Australia aspires to do at least once … but all too often, once is never enough.

You start at the famous Scenic World in the idyllic town of Katoomba and experience a mix of terrain - mostly single track and wide trails - and a mix of emotions as you run through the very special World Heritage listed national park of the Blue Mountains.

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


The UTA100 has 7 checkpoints along its route, with differing levels of service, support crew access and supplies. The UTA100 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 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. For UTA100 runners, your gear will need to be checked pre-race.
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 4, 5 and 6 (these checkpoints can be accessed with a standard 2-wheel drive)
  • For safety reasons, support crews are not allowed at, or anywhere along Glenraphael Drive/Narrow Neck, Checkpoint 1 or Checkpoint 2 or Checkpoint 3, even just to spectate.
  • Support crews cannot drive, ride or walk on any section of Glenraphael Drive/Narrow Neck.
  • Support crews cannot drive, ride or walk along Megalong Valley Road
  • 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.
