Carrera de Navidad San Gregorio is a Christmas Eve running race in Calera y Chozas, Toledo. It is a local holiday race, not a single-distance headline event, with entries open across all categories.
The race is part of the Gran Premio SOLISS, placing it within a wider regional race circuit. The San Gregorio name provides local identity, and the Christmas Eve timing makes it a community race for runners closing out the year together.
