Okay, in the mid 80s there was a movie about the daughter of a trainer that the son of the owner, big farm owner tries to rape. The barn burns, yada yada, she comes back years later a rich widow or something, buys a place, hires a recovering alchoholic, the rich guy tries to run her ot of the neighborhood and they end up with a horse in the Derby. Best line ever was when the girl jock turns to the a$$hole jock and says "I may be a girl, but I'm not the only mother out here"
Second movie, I barely remember, but it involves a girl and a no hoper and there are horse trails at the track, looks like CA or FL and two guys racing almost run her off the trail? I think sh elived with her grandparents or something
Re: your first one, I only saw it the once on the original TV run, and I'm not sure I saw it all then anyway, but possibly the Cheryl Ladd-Wayne Rogers miniseries _Bluegrass_? All I remember clearly is that Ladd's character bets the farm (literally) on her colt in the Derby at the end, but I also seem to recall Shawnee Smith in one of her earliest roles as a spunky female jockey, and that one small part would fit in with your recollection.
Yeah, I was guessing Bluegrass... I remember starting to watch it as a kid, being all excited about a horse movie, and then freaking out at the barn fire. I can still picture it. ): Never made it past that part...
