Hi,
https://www.openstreetmap.org/way/1341056569 does not look like a complete horse riding centre, it looks like an outdoor arena. In OSM riding arenas are usually tagged with leisure=pitch + sport=equestrian, example: https://www.openstreetmap.org/way/1074238514, see also https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding
