San Silvestre Almendralejense takes place in late December in Almendralejo, within Spain's Badajoz province, rooted in the local end-of-year San Silvestre custom. It is a community race rather than a competitive championship, attracting around 1,700 runners and over a thousand spectators annually.
The event features a 3 km non-competitive run, aligning with its inclusive and participatory nature. Residents use it to conclude the sporting year with running, camaraderie, and holiday cheer, while proceeds benefit Club Atletismo Almendralejo and its local youth sports initiatives.
