Cool start — fast day potential

A cool 41°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 51°F through the course will gradually increase perceived effort in the second half. Moderate humidity at 77% is worth noting for effort level, especially in later miles.

About the Boundary Bay Half Marathon

The Boundary Bay Half Marathon is an out-and-back run along the Boundary Bay dike trail in Delta, British Columbia. It starts and finishes at Centennial Beach in Boundary Bay Regional Park, follows a short stretch of Beach Grove Road, then continues on flat gravel oceanside trail to a turnaround just south of 88th Street. Runners get open views over the bay the whole way and pass the same aid stops and washrooms in both directions.
