https://www.openstreetmap.org/node/11676127044 makes sense, but https://www.openstreetmap.org/way/1256123257 isn't a riding centre; it is a riding arena (leisure=pitch + sport=equestrian); it probably belongs to the riding centre which is now represented by the node. Compare https://wiki.openstreetmap.org/wiki/How_to_map_a#Riding_centre_(equestrian) and explanations mentioned above.
