Nah; he has 2 Derby entries, so connectioms clearly think him capable at 12f.
His half-brother (by Galileo) ran twice @ 14f btw.
I’d say 10f at the most;
My Reasoning for that assumption is as follows:
The female line is equally as important when you're talking about stamina or lack of it.
Danehill, (Grandsire) has never been accredited the title, Chef De Race, and that’s despite many people calling for him to be so. To be a Chef, their offspring must show a propensity for at most; 2 aptitudinal groups. Danehill’s progeny are too evenly spread over the full spectrum. What they do show though, is a leaning towards what the tail line breeding influences.
Danehill Dancer, the son of Danehill and the Dam sire of Ace Aussie was a top-class 6/7 furlong horse. Queenscliff, the Dam of Ace Aussie only won up to a mile, her Dam, Bonheur, was a 6-furlong sprinter out of Royal Academy, himself a (Brilliant/intermediate Chef) top-class sprinter that didn’t quite get a mile. Bonheur’s Dam, Queen To Conquer was out of Kings Bishop, another Brilliant/intermediate Chef.
I’m not saying Danehill’s progeny can’t themselves produce horses with enough stamina to stay the Derby distance. Indeed not, take Dancing Rain (Mare, won the Oaks) for example, her Dam, Rain Flower was a daughter of Indian Ridge (intermediate sire) who is very much in the same mold as Royal Academy. The difference here though is, the big stamina influence running through the tail line from Alleged. You might say, but Alleged is not a Chef either, arhhh…Therein lies the importance of reading of the breeding, not just the scores on doors, or in this case, the Dosage. Alleged Has very high scores on his Professional aptitude and though this doesn't count in the overall Dosage index's of his subsequent offspring, he still sheers stamina right through them.
The Entire bottom half of Ace Aussie’s pedigree point’s to Intermediate Aptitude. I’d say he will be best at around a mile to 11 furlongs, and the faster the ground, the better.
