About
Road 5km along the Great Lakes waterfront trail and mixed-surface bike path, starting near St. Lawrence College with a short dirt section then mostly asphalt. Community-driven and volunteer-supported, the course offers open waterfront views and a friendly, small-field atmosphere with post-race bag return and an awards ceremony.
