Race Info
The Boundary Bay Marathon takes place each November in Delta, British Columbia, starting and finishing at Centennial Beach. It offers marathon, half marathon, 10K, and 5K distances plus a four-person marathon relay, all run as an out-and-back on a flat gravel oceanside trail along the Boundary Bay dike. The Boston-qualifier-certified marathon is typically the last BQ race of the calendar year. Proceeds benefit Ronald McDonald House BC and Yukon. Source
