His most consistent working relationship is with trainer John Patrick Ryan, and it is here that Aherne looks most comfortable. Of his 14 rides for that yard, 1 has ended in victory — a win rate of around 7%, or 1 in every 14. That's noticeably better than his overall average, which suggests Ryan knows when to put Aherne up and Aherne knows how to repay the trust.
Perhaps the most interesting detail in his record is what happens when the weather turns ugly. On very wet, muddy ground, Aherne has won 1 from 9 races — an 11% win rate, or roughly 1 in every 9. That might not sound dramatic, but it is more than double his overall average, and in racing that kind of pattern is worth paying attention to. Some jockeys just have a feel for horses that need to dig and grind through deep ground, and the numbers suggest Aherne might be one of them. When the rain is hammering down and conditions are testing, he is a more dangerous booking than his headline figures imply.
At 5% overall, he is not yet among the names punters seek out in a racecard. But the trajectory is upward, the wet-ground edge is real, and four years in is still early. Jockeys can take time to click.
