Register for Grunnduro 2025

In two days you cycle 150km or 250km. Both routes start and end in Groningen and meet halfway at the same green campsite. So you can choose per day whether you want to cycle 75 or 125km, that's so relaxed. Dinner, camping pitch and breakfast? We'll take care of it!

All you have to do is ride a bike and enjoy the best dirt trails and nature in the north. Don't forget to bring your sleeping gear
