39th Heizomat Altmühlseelauf

The 39. Heizomat Altmühlseelauf is a community road running festival held at the SV Unterwurmbach sport grounds near the Altmühlsee, organised by SV Unterwurmbach e.V. The event day on 18 July 2026 features a programme for adults, youths and children, including a half marathon listed as the Altmühlsee-Halbmarathon and a range of shorter fun and relay races. The organiser highlights Heizomat as the principal sponsor and provides official information, maps and registration links on the event website.

The half marathon is an officially measured, single-loop course that circles parts of the Altmühlsee and returns to the sports facility; kilometre markers are in place and a course profile is published on the organiser site. In addition to the half marathon there are a corporate-staffel relay, a 7.4 km Jedermannslauf, youth and children's races, and finisher medals and class prizes for top finishers. The event is promoted locally and connected to the Fränkische Seenläufe event branding, offering a scenic lakeside route for evening racing and strong community involvement.
