Keep Smiling Run is a city run in central Herning, with the start and finish located downtown. It takes place in September and features four distances: a 1 km children's race, 5 km, 10 km, and a half marathon, allowing families, casual runners, and experienced runners to participate.
The route crosses Herning’s streets, urban areas, and green spaces, accompanied by music and encouragement. The shortest race is designed to be enjoyable and secure for children, while the longer distances offer choices from a 5 km challenge to a half marathon. The event emphasizes its name: organizers refer to it as Denmark’s happiest city run, focusing on smiles, community, and city-wide participation.
