Race Rules

Race Course

The course will pass through remote areas. The course will comprise single track, dirt road, and tarmac. It will be marked using direction arrows, event tape, and marshals. At each decision point (which way now!) the course will be marked. If you ride for a long distance without seeing any marking tape you should turn around and go back to the last marking tape you saw. If you are able to download the course (sent by email one week prior t0 the race) onto a GPS device or phone that may provide reassurance, but you should not need to rely on it.

Please remember:
You must complete the marked course under your own power. You must stay on the marked course. Short cuts are not permitted. If you get lost return to the last sighted marking. Littering is prohibited.

Water/Aid stations/Checkpoints

There will be water and bananas available at all aid stations. All other food you will have to carry for the duration of the race. Call out your number when passing checkpoints to help our staff. Outside assistance from supporters is not permitted.


You are responsible for your own bicycle repairs during the race. Please bring any necessary items such as tubes, pump, lube, tools, extra brake pads etc. that you may need. See the mandatory gear list.
There will be no mechanic service provided on course, however a wash and lube station will be available on at least one of the stages following a water crossing. It’s a good idea to take advantage of the lube station to prevent problems later in the race.
