24. Röntgenlauf

The Röntgenlauf is a landscape running event in Remscheid, Germany, held annually on the last Sunday of October since 2001. Its primary race is a 63.3 km ultramarathon, precisely one and a half marathon distances, with a marathon and a half marathon also offered. The event caters to various participants: shorter races range from 400 meters to 10 km near the Hackenberg Sports Center, with Nordic walking and walking categories available from the half marathon distance upwards. A 13.3 km Nordic walking race and a relay, dividing the ultramarathon into three half-marathon legs, are also part of the program. Over 4,000 athletes typically participate. Most longer routes utilize the Röntgenweg, a looped trail encircling Remscheid. Participants begin at the Hackenberg Sports Center, complete a brief loop through Lennep’s historic town center, and then proceed counter-clockwise along the Röntgenweg. Half marathoners conclude their race in Clemenshammer, marathoners commence there and return to Hackenberg, and ultramarathoners finish the entire loop. The course involves significant elevation changes: approximately 850 meters of ascent and descent for the ultra, and the marathon features close to 1,000 meters of climbing. Hackenberg serves as the central hub, featuring award ceremonies, side events, food vendors, and spectators congregating in and around the sports hall. The event also includes the German Marathon Championship for Doctors and, every five years, a 100 km race.
