Roll out from Parkeerplaats Kunsterspring and let the ride unfold: first the Kunsterspring nature reserve, then past the Kalksee and Zermützelsee lakes, and along the Rhin river before looping back to where you started. Of the 49.3 km, most runs unpaved, with 240 m of climbing along the way. It's a route that keeps changing under your wheels and ends right back at the start.
