Trail Marathon Heidelberg

Trail Marathon Heidelberg begins and ends near Karlsplatz in Heidelberg’s old town, then directs runners from the city into steep forest trails above the Neckar. This mid-September trail running event in Germany offers several distances: a 6 km run, the 20 km Base-Trail, the 30 km Half Trail, marathon-distance races of approximately 42 km and 45 km, and a 50 km ultra. The event holds UTMB Index status and iTRA points, attracting runners focused on mountain and ultra-trail rankings, as well as those seeking a local trail challenge. The longer courses are single-loop routes with significant elevation gain: around 900 meters on the 20 km, 1,340 meters on the 30 km, 1,800 meters on the 42 km, and 2,200 meters on the 50 km. The 42 km route primarily follows uneven forest paths and trails, ascends three peaks, and features the Himmelsleiter after about 35 km: an 850-step sandstone staircase leading to the Königstuhl. Along the course, runners pass Heidelberg landmarks and gain wide views over the city and the Rhine-Neckar Delta, but the key characteristic is that this is a demanding hill race, not a road marathon with incidental woodland.
