In Jaén, Andalusia, runners compete at night through the city as part of the San Antón festivities, with the race starting and finishing at the Glorieta de Blas Infante. This event, also known as Carrera Nocturna Noche de San Juan, is a free urban road race that has been held annually since 1984. Participation is open to all, with no requirement to be part of a federated athletics club. It started with 180 runners and has since expanded into a large event attracting over 12,000 participants, including elite athletes from Spain and other countries.
The course remains within Jaén, with participants running through streets still adorned with Christmas lights. Spectators hold torches, particularly near the finish line, a tradition linked to the historical San Antón bonfires. Following the race, participants often burn their torches in the bonfires, sing local melenchones, and consume rosetas, a type of popcorn eaten during the celebration. The race's history is reflected in its past winners: Spanish runners were prominent in the initial years, followed by foreign athletes who dominated for a significant period. Notable repeat winners include Juan José Rosario, Gennet Georgis, Carla Sacramento, and Marta Domínguez.
