Who races in the Takamatsunomiya Kinen? (Celebration Mission)

Ive been playing and only really just got around to checking the quests and the last thing i need to do for the Celebration mission is to place top 3 in Takamatsunomiya Kinen. I've read its one of the starter horses races but which one is it? Ive scouted a lot of girls at this point and dont remember which ones i initially started with and would rather not start careers randomly until i come across the specific race.
