La Course pour l'Environnement (​​EcoRun) 2026

La Course pour l'Environnement, or EcoRun, is a Madrid race series held in Casa de Campo, beside the park's large lake. It is tied to World Environment Day and keeps the format simple: a 1.5 km route, a 5 km circuit, and a 10 km option for runners seeking a longer outing. The 1.5 km distance is made for easy participation and can be walked, suiting families, beginners, or anyone who wants to join without racing hard. The 5 km course is open to all levels and is described by the organizers as one of Madrid's prettiest circuits, while the 10 km gives regular runners a fuller run through the green space of Casa de Campo.
