In this episode of The Toughest Finish Line, we meet an extraordinary woman who has redefined what’s possible — setting a new world record as the fastest autistic female in the ironman distance. Marlynne's story isn’t just about speed; it’s about strength, courage, and the power of showing up as your true self.

She opens up about navigating life and sport through the lens of autism, the challenges she’s faced both on and off the course, and how endurance became her way of finding focus. From training setbacks to race-day breakthroughs, her journey is a masterclass in resilience.

This is a story for anyone who’s ever felt different, doubted themselves, or wondered if they truly belonged in the sport. Because sometimes, the toughest finish lines aren’t the ones we cross — they’re the ones we fight to believe we can reach.
