You have tagged the ways as horse racing tracks ( leisure=track + sport=horse_racing ); but a horse cannot race on such small circles or areas, therefore I think sport=horse_racing is wrong here and it should rather be sport=equestrian . And If not only the mapped way can be used for riding, but also the inner area, then leisure=pitch is more appropriate than leisure=track. (Just my opinion)

Ukrainian example: osm.org/query?lat=50.705273&lon=34.696552#map=19/50.705282/34.696781&layers=P

If something is no longer used, you can use the prefix "disused", see disused:=** (But then it will no longer be rendered on the maps.)

Hi,
way/1482650093 and way/1482650096 are too small for racecourses. These areas look like riding arenas and in then should be tagged with leisure=pitch + sport=equestrian instead, like way/1175887026 , see also osm.wiki/How_to_map_a#Riding_centre_(equestrian)

Hi,
way/1479804868 does not look like a horse riding centre ( leisure=horse_riding ); it looks like a horse riding arena, similar to way/1019077795 ( leisure=pitch + sport=equestrian ); see also osm.wiki/How_to_map_a#Riding_centre_(equestrian) . The arena probably belongs to https://haraslarebatiere.ffe.com/ which could be mapped as a separate object (node or area) with tag leisure=horse_riding .

Hi,
way/1478514107 is not a horse riding centre; it is a horse riding arena and should be tagged like this one: way/1384040097 . See also osm.wiki/How_to_map_a#Riding_centre_(equestrian) . In JOSM you can use the preset for sport=equestrian to tag them.

Non so se way/1477377238 sia davvero un campo di equitazione ( leisure=pitch + sport=equestrian ); nelle diverse immagini aeree appare in modo diverso. Forse si tratta solo di un paddock -> vedi landuse=animal_keeping . Per il resto sembra corretto. Si tratta di https://www.facebook.com/iltorello14 ?
