The Röntgenlauf is a multi-terrain running event in the state of Nordrhein-Westfalen (North-Rhine Westphalia) in Germany.

Held annually on the last Sunday of October, the 63.3km ultramarathon takes runners largely along the Röntgenweg, a hiking trail around the city of Remscheid which sits in the hills of the Bergisches Land.

The start and the finish line are at the Sportzentrum Hackenberg in Lennep in the eastern part of Remscheid where Wilhelm Conrad Röntgen, the first person to detect X-rays, was born in 1845.

The route is challenging and varied and scenic, and it offers many fine views of the region's rich industrial heritage, for instance of the graceful Müngstener Brücke (Müngsten Bridge), Germany's highest railway bridge:
