Grunnduro 2025

Join us for the fifth edition of Grunnduro on July 12-13, 2025! Experience the most relaxed bikepacking weekend in the Netherlands as you explore the scenic trails and hidden gems of the north on a mostly off-road route.

Over two days, you’ll ride either 150 km or 250 km. Both routes start and finish in the city of Groningen, with a shared overnight stop at a cozy, green campsite. Each day, you can choose between cycling 75 km or 125 km—flexible and fun! We’ve got your dinner, campsite spot, and breakfast covered.

All you need to do is ride, explore, and enjoy the stunning landscapes and gravel trails of the north. Just don’t forget to bring your camping gear!
