On Saturday June 20th and Sunday June 21st 2026, it’s up to you to take up the challenge and complete a triathlon. For the 10th year in a row, TRI ROTTERDAM will be organised for both novice and more trained triathletes! There will be a Sprint and Standard distance on the programme this year. In addition, there is also a race especially for youth and juniors, the Junior Challenge. The young athletes will swim 250m, cycle 10km and run 2.5km. There is also a series for the very youngest for the first time this year. In categories 8+, 10+ and 12+, the youngsters will swim 100m, cycle 5km and run 1km.

For beginner athletes, we offer the Rookie Race (500 meters of swimming instead of 750 meters), and to help you prepare for it, we’re offering transition clinics in collaboration with PROschema.

The Willem Alexander rowing course in Zevenhuizen is the heart of TRI ROTTERDAM. This unique venue breathes top-level sports and offers your supporters a great opportunity to follow your race. From the start and finish area, the swim, bike, and run courses—as well as the transition zone—are easily accessible. TRI ROTTERDAM promises to be a spectacular celebration!
