Below is the race profile for the 50mi race:

Mandatory Gear

  • Telstra mobile phone
  • GPX course files on GPS device or smartphone.
  • Whistle for emergency signaling.
  • Reflective vest or clothing for nighttime visibility (if applicable).
  • Headlamp or flashlight with extra batteries (for night portions).
  • Personal identification and emergency contact information.
  • 1 litre of water minimum

It is a requirement that all runners carry a mobile phone throughout the race. Please be aware that reception is very patchy if not with the Telstra network.

It is also a new requirement (as of 2022) to have the GPX file loaded on a smart phone for course following (in addition to course loaded on to your watch where applicable).  We would highly recommend using the GAIA app (details below).

Weather conditions can be variable at this time of year. Runners should bring gloves, a beanie, running tights or thermals and a jacket for night time and possible wet weather running. Runners will need to carry adequate nutrition supplies between aid stations.

There are long sections where runners will need to be self-sufficient between drink stations. This will mean runners will require at least 1 litre of water to be carried between aid stations. Slower runners will require more.

Any runners expecting to take longer than 11 hours to complete the event should ensure they carry a torch after 3pm.

Bibs must be clearly visible at all times.

Finshers medal and presentations

Presentations will occur as follows at Nanga Bush Camp HQ. Times may vary for 50km/50mi events, dependant on all place getters (1/2/3 male & female) having finished their race:

  • 50km at 2pm Saturday
  • 50mi at 4pm Saturday
  • 100mi at 12pm Sunday.

All finishers will receive a WTF finishers medal as they cross the finish line.

Those who complete the 100mi in under 26h (male) and 28h (female) receive a belt buckle, awarded at the presentation ceremony.

Drop bags & Aid Stations

There are three on-course aid station locations:

  • Aid 1 is on Leg 1, and is passed three times. Not accessible by crew. No drop bag
  • Aid 2 is on Leg 2, and is passed two times while running that leg.  Drop bag available.
  • Aid 3 is on Leg 3, is passed two times while running that leg, unmanned, water drop only, No drop bag, accessible by crew.
  • Nanga Bush Camp HQ, and is passed at the end (and therefore start) of each leg. Drop bag available.

Please mark your bags to show whether you’re a 50km, 50mi or 100mi runner (this will ensure your drop bag is returned from the aid station at the appropriate time). You may leave a larger bag (clothing etc) at the Race HQ (Nanga Bush Camp), as runners pass through this when transitioning between legs 1, 2 and 3, in addition to having a drop bag.

Aid stations will have basic supplies of water, coke, lollies, chips and gels with hot food options generally available at NBC for 100mi runners after the half-way point.  Nanga Bush Camp HQ has a full kitchen, cold storage and showers.

Support Crew

Support crew can assist runners at:

  • Nanga Bush Camp (race HQ, start/finish of each leg)
  • Nanga Brook Campground (Leg 2 aid station)
  • River Road aid station (Leg 3)

Access is limited to the other aid stations:

  • Leg 1 aid station: It’s a gravel road to Scarp Pool, then you’ll need to cross the river to get to the track. Not recommended if there’s been recent heavy rainfall. Please pay attention during the race briefing (and in the newsletters ahead of the event) regarding this access, however we would strongly recommend that you make no plans for crew to attend this location regardless.
  • Leg 2 aid station: park at Nanga Mill and or Stringers and walk in. Navigate to Stringers. Park entry fees apply. Or park at the entry station/Trees Adventures and walk in 1km. Please don’t block traffic as Nanga Mill is very busy at this time of year.
  • Leg 3 water drop: can be accessed by River Rd, the Dwellingup side of Lane Pool, no access from Lane Pool entrance, the road is blocked.

Note: no assistance may be provided to runners outside of the official aid station locations – penalty is DQ.


100mi runners may have a pacer from the half-way (50mi) point.  Pacers must carry all required mandatory gear, and may not “mule” for their runner (i.e. runner must still carry their own pack, hydration etc).

No pacers are permitted for the 50mi or 50km events.


The course will be flagged with signage at cricital intersections.

This is a moderately difficult event, and a key requirement is that you have experience with navigating in remote locations. Visit the Course Files page to download GPX files.

Runners should be able to self-navigate using GPX files on watch and/or phone.  If you have a modern GPS-enabled watch with course following, ensure that you have the course loaded and are familiar with using that feature in-advance of the event.

On an iPhone or Android Phone, you can follow the course (offline) using a number of different apps. Carriage of smart phone with such an app is mandatory as of 2022.  GAIA GPS is recommended (no reception is required, you can have your phone in plane-mode to extend the battery life).

Loading the course to GAIA

From the app store on your smartphone, install the Gaia GPS app. Free version is adequate.       Android               Apple

  • Navigate to the course files page from your phone
  • Download the relevant files, find them on your phone, open with GAIA app.
