Ironman 5150 Westfriesland

IRONMAN 70.3 Westfriesland begins with a 1.9 km swim in Hoorn's old harbor, a historic North Holland town. This half-distance IRONMAN triathlon includes 90 km of road cycling and a 21.1 km run, typically scheduled for late June. The course is flat and fast, appealing to athletes aiming for a quick time and those advancing to the 70.3 distance. Following the harbor swim, the cycling and running segments traverse the Westfriesland landscape, featuring windmills, polders, dikes, green countryside, historic town centers, and both old and contemporary Dutch villages. Organizers describe it as an “Authentic Dutch Experience,” a fitting label for the route. The event offers qualification spots for the IRONMAN 70.3 World Championship, attracting competitive age-group athletes alongside regular triathletes drawn by the fast course.
