Kalpana’s sire Study Of Man, Forever Young’s sire Real Steel, and Zeffiro all share the same pattern: Deep Impact crossed with the Miesque female line. There are far too many top horses from this family to list, and there’s probably no need.
This is simply my current view of Real Steel’s progeny.
Their clearest sweet spot is 1,800m and above, especially on courses with long straights. Through last year, backing every male Real Steel runner over 1,800m or further on JRA turf would have produced a win-bet ROI above 120%. That figure should still be above 100% overall now.
When the dam’s side has a strong dirt influence, they can be excellent on dirt too, again particularly from 1,800m upward. They tend to perform especially well at tracks with long straights, and watching the horses themselves, I often feel sustained speed is their main weapon. You can see something similar in Kalpana and Forever Young. Their strength is less about one instant burst of acceleration and more about producing a long, strong run. Of course, that doesn’t mean they’re no good unless the straight is long.
More abstractly, they are driven by power, physical reserves, and their own willingness to run. They can also be mentally unstable and rather awkward, which seems to favour male runners that can force their way through a race.
As mentioned above, 1,800m and further suits them, but their results begin to drop beyond 2,600m. Their main range is 1,800m to 2,400m. Physical strength is a major asset, though their actual staying capacity may not be as large as it first appears. On turf, I suspect the ideal type isn’t too big.
They don’t seem especially resistant to fatigue and can feel the effects of a hard race. A long layoff isn’t necessarily ideal either, so they can be quite effective when returning from a short break. Their form also tends to become less consistent as they get older.
This is specifically about JRA racing, but their record at non-core distances is far better than at the standard distances where sharper acceleration is often required. The win-bet ROI at those distances is over 200%, which is quite remarkable.
Their turf record is also better when the ground is wet. Heavy going can be welcome because other horses struggle more. Above all, they want a race that doesn’t demand sudden acceleration.
They also perform well when stepping up in distance from their previous start, with a win-bet ROI above 100%.
