Hafkamp Groenewegen De Ronde Venen Marathon

The Hafkamp Groenewegen De Ronde Venen Marathon starts and finishes in the center of Abcoude, a village about 3 km south of Amsterdam. It is a November running event in the municipality of De Ronde Venen, with a full marathon, a duo marathon, a 10 km race, and a mini-marathon. The full marathon is a paved, single-loop course through the Groene Hart, the green rural area between major Dutch cities. The duo marathon gives two runners one marathon to share, with partners alternating between running and cycling. The course visits all eight villages in De Ronde Venen and mixes village roads with open countryside. Runners pass rivers, meadows, a former railway line, a cattle farm, and the Botshol nature reserve. The official description calls the route fast and varied, which fits a course that keeps changing without leaving the flat Dutch landscape. The De Ronde Venen Marathon Foundation organizes the event, and the race is aimed at both recreational runners and more competitive runners who want a full-distance road marathon close to Amsterdam.
