Der kleine Karl is a sprint triathlon in Ingelheim, developed as a smaller version of the Ingelheimer Halbe. It begins and ends near Stadion Am Blumengarten in the city center, placing the race within the town rather than on a distant course. Following its initial running, athletes, the city, and the organizers responded positively, with accounts of a good atmosphere surrounding the Ingelheim sprint triathlon.
The cycling portion utilizes Konrad-Adenauer-Straße between the Am Großmarkt roundabout and Rheinstraße, then proceeds on Max-Planck-Straße and Otto-Hahn-Straße towards An den Wiesen. The run covers a 5 km route on service paths in the polder area. On race day, police and course marshals restrict access to the cycling and running segments, and even city bus line 612 alters its route. This indicates a compact yet genuine town event with thorough race-day management.
