Dutch Triathlon Series - Haarlemmermeer

About the race

DTS Haarlemmermeer is held in the Haarlemmermeerse Bos near Hoofddorp, with the sandy beach on the recreational lake as the race site. That is where the swim begins; the bike course then leaves the woods for the broad, entirely closed roads of the municipality. The run passes the lake, goes through the Groene Weelde around the Spotters pyramid, on through the Prins Bernhard Bos and across the grounds where Mysteryland is held. There are three distances: sprint, Olympic and the middle distance, which is on the programme for the first time in 2026. The site is wheelchair-friendly, dogs are welcome on a lead and parking is free.
