Hi,
Why did you tag https://www.openstreetmap.org/way/1230325633 with leisure=horse_riding (for riding centre) and https://www.openstreetmap.org/way/1228873246 with leisure=pitch + sport=equestrian (for riding arena)? I think they are both riding arenas. Compare https://wiki.openstreetmap.org/wiki/Tag%3Aleisure%3Dhorse_riding
