Hi,
https://www.openstreetmap.org/way/1305952910 is probably not a riding centre (tag leisure=horse_riding), on Bing it looks like an outdoor riding arena. In OSM such riding arenas are usually tagged leisure=pitch + sport=equestrian, like this one: https://www.openstreetmap.org/way/958788213; compare https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding
