Course details
Race Roster and Tidal Force describe a 6.7 km loop that is roughly one-third asphalt and two-thirds fine crushed gravel, crossing two bridges, two boardwalks, and a covered bridge around the Petitcodiac River. Each loop begins and finishes at the Riverfront Gazebo on the Riverfront Trail. About three-quarters of the course is lit; a halfway safety checkpoint operates on the Moncton side during the night portion.
