Hi,
the areas
https://www.openstreetmap.org/way/1409714101 and
https://www.openstreetmap.org/way/1409714102 are no horse riding centers; they are riding arenas like https://www.openstreetmap.org/way/1323902001 (tagging: leisure=pitch +  sport=equestrian), see https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding info box at the top.
