Rondjes van Pijn

Rondjes van Pijn is an endurance run organized by IJsvereniging Pijnacker, held on Sunday, September 20, 2026, at the Tinteltent in Pijnacker. The race consists of repeated 4.2-kilometer laps starting every half hour, with a maximum of ten laps. Participants can set their own pace: completing a lap faster means more rest before the next start. The event is aimed at both young people and adults and emphasizes endurance over speed.

Participation is at your own risk; participants are responsible for their own training and insurance. The course is shared with recreational users, and traffic marshals are present at some challenging spots. Dogs are welcome on parts of the course. Repeated 4.2 km laps, maximum distance of approximately 42 km, registration via the website, dogs welcome on parts of the course, and safety and personal responsibility are emphasized.
