Einsiedel-Kressbach-Rossberg

85-kilometer loop with three climbs that can be quite challenging depending on fitness: Einsiedel (short and evenly steep), Kressbach (somewhat longer, moderately steep with flatter sections), and Albtrauf/Rossberg (long but initially gently sloping on the road to Genkingen, then increasingly steep up to the summit). The return route through Reutlingen is rather suboptimal. A detour via Metzingen might be worth considering.
