San Silvestre Onupolis is an urban running event in Huelva, featuring Christmas lights and decorations along the city streets. It offers three distance options: 2 km for younger runners, 5 km for amateurs, and 10 km for those seeking a longer run.
The race is centered on the holiday-season atmosphere, not on a difficult trail or long-distance challenge. Families, casual runners, and dedicated running fans can participate in the same festive street event, selecting the distance that suits them.
