Heidelberg

Heidelberg's runners navigate the Neckar Valley's rolling terrain and the city's steep Philosophenweg climb above the old town; the Neckarlauf stages wind through the valley for 47km stretches between villages. Cyclists dominate here—the Schwetzinger Höllgrund Radmarathon and Gravel des RVA Nussloch draw serious riders into the Odenwald's forested hills and gravel roads just east of the city, with climbs ranging 400–600m over demanding 70–200km routes.
