San Silvestre Vallecana 2026

San Silvestre Vallecana is a 10K race held in Madrid on New Year's Eve, with tens of thousands of participants running through the city streets to conclude the year. While organizers claim it's the best 10K globally, its appeal lies in the shared Madrid night experience for elite runners, first-time participants, regular attendees, and casual joggers alike. The race has strong ties to the Vallecas neighborhood, where some runners compete intensely against the clock while others focus on reaching the finish line with a smile. A Mini Vallecana event for children, conducted with the Gasol Foundation, is also part of the day. The event supports childhood leukemia research through Unoentrecienmil.
