Ended up watching it on Netflix.
The first episode was solid, although there were a few times where I thought the direction (as in camera movement) was lazy. Like in the auction scene.
MC(?) actor is serviceable and owner picks up the slack well.

I feel that the conceit of MC wanting to make up for 'betraying' his father is kind of a tenuous starting point to 'save the horses'. Maybe the novel communicates it better, or maybe I'm just dumb.

Maybe I'm just a softy nowadays, but the old dude's outpouring of gratitude when Fight placed was good.
And of course, the keiba stuff was fun.
I hope the corporate B-plot doesn't take too much away from hors.
