San Silvestre de Lerma 2026

San Silvestre de Lerma is a running race held in Lerma, Spain, within the province of Burgos. The Plaza Mayor functions as the start and finish line. This race is part of the San Silvestre tradition, placing it on the late-December calendar instead of the typical spring or autumn road-racing season. The Ayuntamiento de Lerma organizes the event, which is classified as a mass-participation athletics race, not exclusively for elite runners. This marks the twenty-fifth running of the Lerma edition, establishing a local history that extends beyond a single holiday event.
