From the Promoter:
A laid back gravel event in the Lowlands of Europe. At the finish, a beer and burger party in an old summer theater. The route covers sand paths and roads, gravel roads, cobblestones and tarmac. Roughly 70% of the routes are unpaved. We had a cyclocross / gravel bike in mind when selecting the routes, so please bring a bike with at least 28mm wide tyres.
