Quitting is not an option!
5,000 cyclists, alone or in a team, will climb in one day up to 6 times the ascent of Alpe d’Huez and its legendary 21 bends. An event that is mythical and renowned in the Netherlands for its 14 km and 1120 meters of vertical drop. By bike, running or walking, the aim is to cover a maximum of 84 km and 6700 vertical meters in the same day! The objective of these six climbs (Zes meaning 6 in Dutch) is to collect donations for the KWF, the national and official foundation in the Netherlands for the fight against cancer.
