St. Lawrence Marathon registration surges: 650 runners signed up in first week, over 70% of spots already claimed

January 13, 2026

CORNWALL, ON — One week after opening registration, the St. Lawrence Marathon has already welcomed 650 registered runners, filling more than 70% of its total spots for race day on Saturday, April 25, 2026.

The event features four race distances — 5K, 10K, Half Marathon, and Full Marathon — and draws runners from across Eastern Ontario, Quebec, and beyond to experience a fast, scenic route along the St. Lawrence River.

“Seeing 650 registrations in the first week is incredible,” said Sebastian Warner, Race Director. “It tells us people are hungry for a well-run, community-powered event — and if you’re thinking about joining, don’t wait. We’re on pace to sell out.”

The St. Lawrence Marathon is known for its supportive atmosphere, volunteer energy, and waterfront course. With limited capacity and strong early demand, organizers are encouraging runners and families to register soon to secure their place.
