The San Silvestre Alpedreteña is a New Year's Eve charity race held in Alpedrete, a town in the Madrid region. It marks the end of the year with a local competition, not an elite-only event. About 550 runners can enter, and funds raised benefit adELA, the Spanish Association for Amyotrophic Lateral Sclerosis.
The event includes a 5 km race for those looking to test their speed, and a 2 km option for families, children, and older participants. Many local residents participate, with spectators lining the streets, making the day feel like a community gathering and a sporting farewell to the year. Now in its ninth edition, the race has become an established Alpedrete tradition centered on running for a cause.
