Racing, is indeed, mainly a "mans world".
But, if you have followed Courtney's progress, you can see clearly that she is shooting for that "mans world".
That she is doing so, I hope, will encourage more woman to get out of their "comfort zones", and try to become better and better. I'd hoped that Ashley Fiolek, and other US WMX riders, would make an effort, and try to progress further. Ashley, has / had access to bikes competitive with anything on the line of a US National. But, she's elected to retire - as she has every right to - she's been at racing for a long, long time, and it seems she has chosen to move on. Though, reportedly, she's answered questions about her retirement with "the series sucks". Her ambitions, may have been achieved, and they appear to have been limited to women's racing.
The race on the weekend was reportedly Courtney's first "Pro" race of her career.
She's been reported as having always seen herself as a "racer" - not a WMX racer only.
She's only 17 - she has many years ahead of her, if she continues with her career.
I see no reason that her gender should restrict her from succeeding - talent is not only the province of men on a bike. And, her size should not be a disadvantage - many male MC racers are small.
I wish her well, and hope she gets to the level of success She is aiming for. She's a highly talented Motocross rider, that's at the very beginning of her Pro career.
