Zes uur van de Haarlemmermeer

About the race

In the Zes uur van de Haarlemmermeer you try to cover as many kilometres as possible in six hours. The event by AV Haarlemmermeer is intended for ultrarunners and relay teams and is run on a loop of almost two kilometres around the athletics track in Hoofddorp, with the track itself also part of the course. The race grew out of the former Ronde om de Haarlemmermeer. In 2026 it is the 25th edition and also the National Six Hour Championship of the Netherlands and Belgium.
