Hi,
https://www.openstreetmap.org/way/1435251240 and https://www.openstreetmap.org/way/1435251242 don't look like riding centers, they look like riding arenas (similar to https://www.openstreetmap.org/way/651759043). Maybe they belong to a riding center which in this case can be mapped as a separate object (node or area), example: https://www.openstreetmap.org/way/1421250337#map=17/35.226117/-113.997386&layers=P .
