21.1 km through Heidelberg's Old Town, across the Old Bridge and along the Neckar
The ATOS Heidelberg Half Marathon is one of Germany's most beautiful city runs. Organized by TSG 78 Heidelberg, the race starts punctually at 9:15 AM on Sunday, April 26, 2026, on Friedrich-Ebert-Anlage, near the University Library. The 21.1-kilometer course leads through the medieval Old Town, across the famous Old Bridge, along the Neckar riverbank, and over the scenically spectacular Philosophenweg with views of the castle, back to the city center. The finish line is at Universitätsplatz — with musical entertainment to welcome the finishers.
The 2026 edition recorded 3,768 finishers (2,575 men, 1,193 women) — a remarkable number for a city half marathon of this scale. Heidelberg attracts runners from all over Germany and Europe with its unique course. The historic route passes landmarks such as the castle ruins, Kornmarkt, Heiliggeistkirche, and Karlstor.
In addition to the main race, there are two accompanying runs: the Henkel Team Run over 3.1 kilometers is aimed at corporate teams and hobby runners; the DGZ Bambini Run over 1,200 meters is for the youngest athletes. These accompanying runs make the ATOS Heidelberg Half Marathon a family-friendly city sports event that appeals not only to professionals and competitive athletes.
Heidelberg is an independent city on the Neckar in northern Baden-Württemberg, with approximately 162,000 inhabitants. The university city — Ruprecht Karl University is the oldest university in Germany, founded in 1386 — is one of the world's most famous tourist destinations, characterized by its castle ruins, the Old Bridge, and the baroque Old Town. The half marathon course makes optimal use of this postcard setting: every kilometer passes a sight. The ATOS Heidelberg Half Marathon is one of the major events in the city calendar, alongside the Heidelberger Frühling and the Castle Illumination.
