Roll out of Rogätz and straight into the Elbaue nature reserve, then past the Ohremündung reserve and the Klutturm castle. The Ohre river and Neustädter See lake keep you company before two castles, Wolmirstedt and Angern, line the way home. It's 70.6 km, almost all paved, with 196 m of climbing — back to Rogätz before you know it.
