Hearing that you suffer from a potentially lethal heart condition is truly a life-changing moment. Some people who are unlucky enough to hear this news spend the rest of their lives carefully managing their diet and avoiding strenuous activity. Then, there are a select, elite few who attack life with renewed vigour.
These are the heroes who are the subject of HEART: Flatline to Finish Line, a documentary that follows a team of 'cardiac athletes' as they train for one of the world's toughest endurance competitions.
Every member of the team has been treated for a deadly heart disease or defect, and one has technically been dead for over five minutes, but they are throwing themselves into one of the most physically demanding races on earth.
The trailer introduces members of the team as they discuss their heart problems, something that they share with over 80 million people in America. But the clip goes on to show what sets them apart from most other cardiac patients.
They've volunteered to swim, bike and run the ultimate triathlon, Ironman Arizona, 140.6 miles of pain and suffering that could either kill them, or be the biggest triumph of their lives.
As the trailer makes clear, the athletes will rely on their hearts. Not just the muscle pumping blood to their tired limbs, but also the will to go on when everything tells them to stop and the determination to take just another step towards the finish line.
While there is optimism in the trailer, touting the inspirational tales of each althete, it also makes starkly clear that the competitors may well be taking their lives in their hands, quite literally.
The trailer has earned over 3,400 views, but the final project will not be finished until Summer 2013. Those keen to see the finished film can donate to help with the production and a percentage of all proceeds raised from it will go to heart charities.
