Carrera de Navidad Alerre is a Christmas-season running event in Alerre, a village in the province of Huesca in northern Spain. The listed race option is a 7.5 km run, and Buscametas marks it as non-competitive, suggesting it is more of a local festive run than a results-first road race.
The public listing provides the basics: Alerre as the host town, a December slot, a dedicated event website, and contact links for organizers. Classifications are shown on the event page when available, but the listing also lets runners request alerts for confirmed scheduling and results, which is useful for a small local race with details still being finalized.
