The Grebbe Tourtocht begins in Driebergen, offering cyclists five route options: 30, 50, 80, 110, or 140 km. This is a road cycling tour, not a closed-course race. Participants navigate using GPS tracks or detailed route notes through the Grebbelinie area and the Gelderse Vallei.
The shorter family route winds through the woods between Driebergen and Maarsbergen, suitable for e-bikes. The longest route extends to Bennekom and Renkum before returning via the Grebbedijk. The course passes the Valleikanaal, Wageningen, the rear of the Grebbeberg, Rhenen, the Amerongseberg, the Nederrijn area, and the Langbroekerwetering. The Grebbelinie, which defended the Netherlands for almost two centuries and has had parts designated a National Monument since 2011, adds a unique dimension to the event.
