Contestants will be completely self reliant from the start of the race until the end, and will need to carry their food and equipment on their backs. Water stations and medical tents will be provided at 20km intervals along the route. Temperatures are expected to be in the region of min 5ºc / max 40 ºc but could be more extreme.
