Hi,
How could the small round areas
way/1159124515
way/1159124516
be used for horse racing?
I assume they are round pens. In this case I would recommend leisure=pitch + sport=equestrian (preset for riding arenas).

Hi,
You have removed the building tag from this building; there it is no longer visible as a building on the map.
Also the tag leisure=horse_riding is not for specific buildings but for the whole area of the riding centre, see
osm.wiki/Cs:Tag:leisure=horse_riding
way/996881706

Hi,
an relation/5505101 hast di das building=yes entfernt, deswegen ist das jetzt nicht mehr als Gebäude auf der Karte zu sehen.
Mit leisure=horse_riding sollte man auch keine einzelnen Gebäude, sondern das ganze Gelände von dem Pferdehof taggen, siehe
osm.wiki/DE:Tag:leisure=horse_riding

Hi,
I think, version #1 of way/1158569480/history was better than version #2; this area isn't large enough for horse_racing. And the tag leisure=horse_riding is not for stables, indoor arenas, etc. but for the whole facility, so I think it is misplaced on way/1158569477 and way/1158569478
Compare
leisure=horse_riding

Hi,
This is not an equestrian centre, it is just a riding arena, see osm.wiki/FR:Tag:leisure=horse_riding

Hi,
way/1157643648
and
way/1157643649
look like riding arenas and not like riding centres.
Riding arenas should be tagged leisure=pitch + sport=equestrian.

Ciao,
way/1157643648
e
way/1157643649
sembrano arene di equitazione e non centri di equitazione.
Le arene di equitazione dovrebbero essere etichettate come tempo libero=pitch + sport=equestre.

Hi,
You have removed the tag building=yes from
way/186455386
way/186457318
way/186459012
way/186458264
and replaced it with leisure=horse_riding (riding centre). This makes no sense and has caused the buildings to disappear from the map. Every building should have a building tag. For special types of buildings you can use
osm.wiki/FR:Tag:building=riding_hall
osm.wiki/FR:Tag:building=stable
The the tag leisure=horse_riding is indended for complete riding centres and not appropriate for these buildings that are only a part of a riding centre, please read
osm.wiki/FR:Tag:leisure=horse_riding

Hi,
I don't know what way/1157463346 is, but it doesn't look like a riding centre and maybe @valhikes/diary/401189 (mentioned in weeklyOSM 661) can inspire you.

Stimmt. Entschuldigung.

Hi,
warumm hast du denn an way/204045392 das building=yes entfernt? Auf den Luftbildern sieht es aus wie ein Gebäude.

Here:
https://github.com/openstreetmap/id-tagging-schema#Translations

Yes; this iD preset was recently renamed, see
https://github.com/openstreetmap/id-tagging-schema/pull/780/files
Was that the reason why you didn't find/select it right at the beginning?

Hi,
Isn't way/1156989217 a riding arena? Riding arenas should be tagged leisure=pitch + sport=equestrian, see
leisure=horse_riding
way/1102858584

Hi,
Isn't way/1156988475 a riding arena? Riding arenas should be tagged leisure=pitch + sport=equestrian, see
leisure=horse_riding

Hi,
Isn't way/1157081622 a riding arena? Riding arenas should be tagged leisure=pitch + sport=equestrian, see
leisure=horse_riding

Hi,
The wiki says leisure=pitch + sport=equestrian is correct for maneges = riding arenas:
leisure=horse_riding
https://taginfo.openstreetmap.org/tags/sport=equestrian#combinations
https://taginfo.openstreetmap.org/tags/amenity=manège

I see. 'rodeo' comes from this recent change:
https://github.com/openstreetmap/id-tagging-schema/pull/780/files
This should be translated for en-GB to "Horse Riding Arena" like it was before. I will have to look into that (if you don't want to do it yourself).

Hi again,
Isn't way/1156228833 a riding arena? You have tagged it as a riding centre (tag leisure=horse_riding). Riding arenas should be tagged leisure=pitch + sport=equestrian (iD-preset Horse Riding Arena). See also
leisure=horse_riding

Hi,
You have removed building=yes from
way/317638377,
therefore it is no longer rendered as a building.

Hi,
way/1156335444 sieht nicht aus wie eine Reitanlage (leisure=horse_riding), eher wie eine Führanlage (osm.wiki/DE:Tag:animal=horse_walker)
