The Milla Popular de San Antonio is a one-mile road race in Arroyo de la Encomienda, near Valladolid. Run on asphalt, it's a short, fast event on the running calendar: 1,609 meters, suitable for newer runners but also competitive for those aiming to race hard from the start.
The event is organized by C.A. Arroyo and the Arroyo de la Encomienda town council. It features a children's race, trophies and cash prizes for winners, and practical services like showers, giving it the atmosphere of a local athletics meet rather than a large-scale city race.
