San Silvestre de Torrelavega is a running event held in late December in Torrelavega, Cantabria, as the town prepares for the new year. The primary race is for participants aged 10 and older, offering two distances: 3.5 km and 7 km. Both are designated as non-competitive, emphasizing participation over speed.
Additionally, a 1 km race is available for children up to age 10, facilitating family participation. The awards reflect the event's local and spirited character: the top three finishers in each category receive trophies, while awards are also given to the three largest groups and the three best costumes. Organizers frame the race as a community gathering for Torrelavega, combining sport, family, solidarity, and a New Year's send-off.
