Hi,
Why dis you retag https://www.openstreetmap.org/way/94531247 ? On Bing it looks like a riding arena and it was tagged like riding arenas are usually tagged in OSM: leisure=pitch + sport=equestrian. A riding arena is not a riding centre, see https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding

https://www.openstreetmap.org/way/1309163840 also looks like a riding arena.
