The course mixes rocks, roots, wide trails, single track, wooden bridges, creek crossings, hills and meadows. Conditions can vary seasonally and include mud, snow or sun. Organizers discourage the use of headphones or ask that volume be low to allow safe passing.

There are three aid stations on the course stocked with water, Tailwind and snacks. The event is cupless; participants must bring their own flask, speed cup or bladder for refills. Portable toilets are available at the start and finish area. First aid is provided on site.

For the 50 km there is a hard cutoff, headlamps are required for late running, pacers are allowed on the last loop and poles are permitted. Parking is available at Batawa Ski Hill with overflow at the Batawa Community Centre.

The event provides a sustainable handmade medal to all participants, podium medals for first to third male and female in each distance, and participant medals for the kids run. Merchandise and preordered race shirts are available. There are no refunds; transfers between individuals are allowed until October 31.
