The Siegendorfer Rote Nasen Lauf is a small charity 1 km event in Siegendorf, Austria, held as a morning community run. The start and finish are on the Hauptstraße in front of ASV Siegendorf. Laufclub Siegendorf and the Gesunde Dorf Team organize it. It's part run, part walk, and part family outing, with recent fields including people running, walking, and using scooters or rollers.
The course is a simple 1 km loop along the Hauptstraße, allowing participants to cover it at their own pace. The event supports the Rote Nasen Clowndoctors through entry fees and donations. The crowd is very local, with families, children, donors, the municipality, ASV Siegendorf, and local groups all contributing to its success. One recent edition had about 80 participants, following a first edition with around 70 people of all ages. Kinderfreunde Siegendorf provided a face-painting and craft table for children.
