- Briton Charlie Martin aims to become the first transgender driver to race at Le Mans
- She walked away from motorsport fearing she wouldn't be accepted
- But Martin is back competing in the 2019 Michelin Le Mans Cup
- "We need positive stories from real trans people doing incredible things" - Martin
(CNN)Standing amid the fevered atmosphere of the Le Mans 24 Hour race, Charlie Martin had an epiphany.
One day he wanted to race at the iconic French cathedral of motorsport -- home to the world's oldest endurance race that takes place again this weekend -- instead of watching rain-soaked from the sidelines.
But this dream was secondary to another, more urgent desire that beat inside his body like a pulse.
If he raced it would be as a woman.
"Back then I wasn't even racing," Martin explained to CNN Sport. "But if you could have granted me any wish -- apart from changing my gender which was always the default answer -- it would have been to race at Le Mans.
"It is such a festival for petrol-heads and I came away spellbound; it was everything, the feat of endurance, what the cars go through, the scale of it in front of 300,000 fans.
"I said to myself there and then -- that's it."
