Heart: Flatline to Finish Line

How it Happened


First time director David Watkins nearly died on an operating table from complications after open-heart surgery. After recovering, rather than feeling depressed, he decided to kick his life into high gear. Twelve months after surviving a heart-stopping episode and subsequent stroke he finished his first IRONMAN® Triathlon.


After conquering one of the world's most grueling endurance events he began searching the globe for people like him who have serious heart defects but can't help but compete in endurance sport. As momentum built and the Ironheart Foundation formed, he figured, "why not document this?".


The Team


David Watkins is a first time director with a big heart and huge passion for life. His spirit and motivation gave birth to a triathlon team, non-profit foundation and feature-length documentary film. He's a busy guy.
