Dortmund

Dortmund sits in the flat Ruhr Valley with mostly road-cycling terrain; the Haarstrang-RTF and local gravel events like BRT 2026 tap into rural routes east towards the Sauerland foothills, where elevation gains become serious around 50km out. Runners find flat, fast ground through the city and along the Ruhr river, though the Megamarsch Ruhrgebiet 50km night event draws endurance walkers and runners across the industrial region's network of parks and towpaths. For cyclists seeking hills, the Sauerland begins 40km south—otherwise this is a cyclist's base for long, rolling centuries on local RTFs rather than climbs.
