ATOS Half Marathon

The ATOS Halbmarathon 2026 (Heidelberg Half Marathon) is a premier road race organized by TSG 78 Heidelberg, scheduled for Sunday, April 26, 2026. Known for its challenging and scenic route through one of Germany’s most historic cities, the event attracts a diverse field of runners ranging from elite athletes to local families. Alongside the main half marathon distance, the event features the Henkel Team-Lauf and the DGZ Bambini-Lauf, ensuring that participants of all ages and fitness levels can engage in this community-wide celebration of health and movement.

Race Logistics and Preparation

The race headquarters transitions between the TSG 78 facilities on Tiergartenstraße for early bib distribution and the "Neue Uni" (New University) in the city center for race-day operations. To support runners in achieving their personal goals, the organizers host a series of organized preparation runs throughout the early months of 2026. On-site registration and race number transfers are facilitated through specific windows, starting the Thursday before the race to ensure a smooth flow on Sunday morning. Additionally, the event maintains a strong philanthropic component through its "Staffelstab" incentive prize, supporting local athletic development and community projects.

Regional and Community Context

Heidelberg is a world-renowned university city in the state of Baden-Württemberg, famous for its romantic 14th-century castle ruins and its status as a UNESCO City of Literature. The race course typically navigates the narrow cobblestone streets of the Altstadt (Old Town) and crosses the Neckar River via the Alte Brücke (Old Bridge), providing runners with iconic views of the surrounding hills and the Philosophenweg. The city is a hub for scientific research and international academia, being home to Germany’s oldest university, which infuses the event with a global and youthful energy.

The local population of approximately 160,000 is highly active and supportive of large-scale public events. The geography of the region is defined by the steep slopes of the Odenwald forest, which often means the half marathon course includes significant elevation changes that test even seasoned runners. Beyond its academic prestige, Heidelberg is a center for medical innovation, as evidenced by the title sponsorship of the ATOS Clinic. This partnership underscores the community’s commitment to the intersection of professional sports medicine and public wellness, fostering a tradition where thousands of spectators line the Neckar to cheer on the runners in one of Germany's most picturesque urban settings.
