Courses use a mix of trail, gravel, paved roads, road, double track and snowy single track.

Every course is timed and traffic laws apply on open roads.
The event team plans for winter weather, monitors conditions with local authorities, and may modify or shorten routes for safety. Entries can be transferred to another person at no charge.
