Reichenau Halbmarathon 2026

The Reichenau Half Marathon is an autumn road race held on Reichenau Island, the largest inhabited island in Lake Constance. The primary event is a 21.1 km half marathon. The Reichenauer Insellauf also features a 10 km race, a 3 x 7 km relay, and shorter runs for youth and children, catering to a range of participants beyond just half marathon specialists. Sportverein Reichenau organizes the event, with the start and finish located at the Baurenhorn sports field on the island's western side. The half marathon course consists of three shortened laps, while the 10 km race uses a single lap. The route incorporates sections of the shoreline and passes vineyards and historic structures, offering expansive views of the island and Lake Constance. The courses are officially measured and noted in race listings as fast, appealing to runners aiming for a specific time as well as those seeking a contained island race. Reichenau is connected to Konstanz by road, allowing participants to reach the island setting without a ferry.
