Course and rules

The course is a figure-8 single-track trail along coastal cliffs and inland sections with mud, rocks, bog bridging, roots and unstable boardwalk sections. Each lap is about 16.7 km (10.4 miles); 50K runners complete multiple laps and must return to the start/finish area at the end of each lap. The only aid station is at the start/finish area, so runners must be self-supporting on the course. Drop bags, chairs and small pop-up tents may be left in the start/finish area.

Mandatory equipment is checked before each lap and includes a windproof or waterproof jacket, warm mid layer, warm head covering, warm gloves, foil blanket, whistle and at least 200 calories of instant energy; a headlamp is required when starting later laps. Runners must complete the first two laps within 6.5 hours and the overall course time limit is 10.5 hours. A limited camp/parking area is available 600 metres north of the trailhead for up to 12 vehicles with no open fires; a portable toilet will be provided. The event offers a 50% entry discount to Indigenous runners. Visit the organization's website for the most recent information.
