The 2026 diversion replaces the Botshol nature path
The organizer’s October 3 update confirms the November 15 race and explains the current diversion. Older descriptions of an unpaved Botshol nature-path section are unsuitable for this edition. Review the new map before selecting footwear or planning a spectator meeting on the former route.
The revised section leaves Waverveen via Waverdijk, Stokkelaarsbrug and Voetangelweg, then approaches Abcoude from the north. The organizer describes replacement asphalt rather than the old nature trail. Prepare from that current surface mix and expect the rural route to require steady effort when wind or weather changes.
The full marathon and duo marathon use the revised route, while the 10 km retains its route through Baambrugge and approaches Abcoude from the south. Supporters should identify the correct course before choosing a viewing point. A meeting place that works for the 10 km may not be on the marathon’s final approach.
The October update says the duo event is sold out while full-marathon and 10 km entries remain available until early November, subject to capacity. Availability can change, so check the live entry form. The duo’s cycling arrangements belong to that specific category; individual marathon runners should follow their own outside-support rules and final participant instructions.
