The Niagara stop of the Subaru Triathlon Series takes over Nelles Beach Park on the Lake Ontario shoreline in Grimsby. Its shore-parallel, point-to-point swim makes it a favourite for newcomers, and the flat out-and-back bike course toward Vineland is fast and beginner-friendly. Distances range from a full sprint triathlon (500 m swim, 25 km bike, 5 km run) down to a shorter Try-A-Tri, plus duathlon and relay options, making the Grimsby race an approachable entry point into multisport racing each summer.
