Hi,
https://www.openstreetmap.org/way/1284161779 should better be tagged leisure=pitch + sport=equestrian (like https://www.openstreetmap.org/way/951941091) because it is a riding arena and not a riding centre. The riding centre was already mapped as node: https://www.openstreetmap.org/node/11370936481. Compare https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dhorse_riding
