Boundary Bay Marathon 2026

Boundary Bay Marathon 2026 is a late-season road-to-trail style outing at Boundary Bay Park in Centennial Beach, Delta. The race day lineup includes a marathon, half marathon, 10K, 5K, and a 4-person relay, all centered on the same shoreline setting.

The draw here is the flat, gravel, oceanside course and the wide-open views along Boundary Bay. It’s also tied to Ronald McDonald House BC/Yukon, which gives the event a community-minded feel beyond race day.

For runners looking for a BC marathon option in early November, this event sits in a familiar local race hub and pairs a straightforward course profile with a scenic waterfront setting. It also appears on the calendar as a trail race in Delta.

The course uses a flat, out-and-back gravel trail at Boundary Bay Park, Centennial Beach. The marathon route is subject to change because of the Mud Bay Nature-based Foreshore Enhancements project. Start/finish is at 550 Boundary Road in Delta, BC.
