COURSE DESCRIPTION
Narrow Neck, Ironpot Ridge, Leura Forest, Wentworth Falls, Kedumba Pass, Furber 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.
After some lush bushland, beautiful escarpments, epic ridgelines and about 99kms, you’ll stand at the bottom of the most famous set of steps in trail running... just 951 of them are between you and the finish line back at Scenic World.

KEY INFO FOR UTA100 RUNNERS
All the information you need to know before starting an extraordinary adventure.
SUPPORT CREW
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.
