You may produce a low level race horse from this breeding. You could have fun racing that at the low end tracks if that is what you want to do. It won’t make you rich and you could very well lose money, but if it’s a hobby you want and you’re going to be a responsible owner and make sure the resulting foal is taken care of after it’s racing career is over (which will likely be very early in it’s life), go for it.
Not all race horses are created equal.
A horse named Flower Alley ran 14 times in his career. He won $2,533,910, or an average of $180,994 per race. His stud fee is $20,000.
He was bred to a mare named Arch’s Gal Edith. That mare only raced one time, but she pocketed $25,000 for that race. Perhaps she got injured? But her single race was against high level competition and she won. Her family (up close) also has blacktype stakes winners all over the place.
Those two horses were bred and they produced I’ll Have Another, who won the Kentucky Derby last year. His breeding was “low budget” by Derby standards.
For comparison, Lady on a Run ran 15 times in low end races, averaging less than $700 per start. She won 3 of them against similar quality horses. Her sire averaged about $30k per start and she did not live up to his level of performance.
The stallion you want to breed her to, Slip Me A Mickey raced 7 times and averaged just over $6,300 per start. His sire was a “moderately successful” race horse, but in both horses you have to go back several generations to find a horse that was a super star. You’re getting farther and farther away from those talented ancestors.
I’m not saying you shouldn’t do it. Go hang out at the low end tracks. See the claiming races - that’s where a horse of this breeding would be running. If it’s something you’re still interested in doing as a way to be a race horse owner, go for it - but you do need to be realistic about what you are producing.
Honestly, I’d be more interested in that particular foal as a sport horse.
