It's well within the last ten years, which is within the living memory of everyone on here, that 'girl jockeys'/'lady riders' were drawing the ire of male punters for being second-rate pilots, too weak, not aggressive enough, couldn't ride a winner unless they were on much better horses than their male counterparts, etc., etc., world without end. That mindset barely changed throughout the time that Hayley rode winner after winner through her claim, because it then only gave ground by saying stuff like 'oh, all very well today, but let's see her when she's lost her claim/no-one will give her rides', and as for Lisa Jones, Kirsty Milczarek, Cathy Gannon and Amy Baker - pure tokenism or somebody's pet, not 'real' riders.
As much as one could bang on about female riders like the incredibly brave and talented Sheila Willcox from the 1950s' eventing scene, Pat Smythe from 1940s/50s showjumping, and the unsung women trainers who had to hide behind the names of their head lads or husbands - oh, the shame, the shame of the Jockey Club - one was always told oh, yes, they might've been very good, but they couldn't compete in an actual race against Manly Men, where strength and superior brain power would overcome them every time. No point mentioning Julie Krone, then, as that was the USA, and therefore on another planet. "Our girls" would never be that good, yadda-yadda. No point reminding the snipers that at least 50% of a ride-out string would consist of 'girls' up on the the same type of squirly 2 y.o.'s as the 'boys', or the same bit-boring steeplechasers? No, of course not. They were just work riders, nothing like the quality needed to take part in and actually win races.
So, yes, Nina does deserve all credit, not just for her personal competency as a 'woman rider', but as a very good rider, full stop.
I'll take it as read that this forum's grown up where some others haven't, and that by another ten years' time, women jockeys are viewed no differently - good, bad, or mediocre - as the men. Why, by then, they might even be riding serious Classics contenders!
