Roll out of Weilheim in Oberbayern and let the ride unfold: past the Rohrmoos nature reserve, then on through the Schwaigwaldmoos nature reserve, the Oberoblander Filz nature reserve and the Schwarzlaichmoor nature reserve. Of the 63.7 km, most runs unpaved, with 549 m of climbing along the way. It's a loop that starts and finishes in the same village, so the nature reserves come one after another before you roll back home.
