2026 Tidal Force Ultra 100

Tidal Force Ultra 100 is a dusk-to-dawn night run along the Petitcodiac Loop Trail in Riverview on August 22–23, 2026. Organizers describe 15 hourly 6.7 km loops starting from the Riverfront Gazebo on Coverdale Road, with a 7:00 p.m. start and a 10:00 a.m. finish window the next morning, plus cash prizes for the final-loop sprint.

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.
