CxM El Ronquillo offers a 13-kilometer mountain and trail race through the terrain surrounding El Ronquillo, Sevilla. The short-course event commences at 10:00 AM, is included in the Sevilla League, and is put on by the Ayuntamiento de El Ronquillo. It targets trail runners, not road-race specialists, and past editions have had entry limits, for example, 250 participants.
The course crosses the municipality's natural areas, emphasizing off-road running over a flat city circuit. Initial race details indicated Calle Gallego 10 as the starting point, with a later version specifying Calle Nueva 36, both located in El Ronquillo. The series also features a race for school-aged participants around Plaza Divino Salvador, comprising six events: five for official scoring and one promotional event. One past edition charged 10 euros for federated runners and 15 euros for non-federated runners, with bib collection on race day.
