Hi,
https://www.openstreetmap.org/way/1446907064 does not look like a horse riding centre (leisure=horse_riding); it looks like a riding arena. RIding arenas are usually tagged with leisure=pitch + sport=equestrian (like https://www.openstreetmap.org/way/1174236609).

This one also no riding centre: https://www.openstreetmap.org/way/1328528938
