Hi,
https://www.openstreetmap.org/way/1366005685 looks like an outdoor riding arena and not like a riding centre (centro equestre, https://wiki.openstreetmap.org/wiki/ES:Tag:leisure=horse_riding). In OSM riding arenas are usually tagged with leisure=pitch + sport=equestrian, like this one: https://www.openstreetmap.org/way/1131292483
