18th Uhldinger Pfahlbau Marathon

The 18. Uhldinger Pfahlbau Marathon is a single-day scenic running event held on 9 May 2026 with start and finish in the harbour area of Unteruhldingen. The race is promoted as a “Lauf durchs Paradies” and follows shoreline promenades and rural paths past local landmarks such as the Pfahlbaumuseum, vineyards and Schloss Salem. Organised by the local Tourist-Information in cooperation with TSV Mühlhofen, the event offers a range of distances for adults and children and is presented as a community-oriented naturrun at Lake Constance.

Multiple race options are available including a half marathon, 10 km, a short 4.2 km run, a 10 km Nordic Walking course and children’s runs; individual race registration is handled through the datasport portal. The event page notes the start/finish at Unteruhldingen harbour and states the race takes place in all weather, while more detailed start-wave times and entry inclusions are listed on the registration pages. Participants are advised to consult the official registration service for fees, cutoff and late-entry information.
