Hi,
https://www.openstreetmap.org/way/1436119278 does not look like a horse riding centre (leisure=horse_riding), it looks more like a horse riding arena and in this case should be tagged with leisure=pitch + sport=equestrian. Maybe leisure=horse_riding could be moved to https://www.openstreetmap.org/relation/19686734 (?)
