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

Included

There are many rides, but only one is America’s bicycle touring classic; TOSRV. The Tour of the Scioto River Valley began as a father-and-son outing 1962 before quickly growing into (at one time) the nation’s largest bicycle touring weekend.

Typically, about 1000 cyclists participate in the annual  weekend tour. Route options include 50 miles from Chillicothe to Portsmouth Ohio on Saturday and 50 miles back on Sunday. If you're up for the challenge, the 100 mile option from Canal Winchester to Portsmouth is offered on Saturday with a return on Sunday.
