Imagine swimming for 53 hours straight, now imagine doing it in nothing but a swimsuit in shark infested waters while getting stung repeatedly by jellyfish. For Diana Nyad this was not a nightmare but rather the realisation of a dream which she had held for a significant amount of her life.

In September 2013, Nyad proved that one should never give up on their dreams, no matter how crazy other people think you are when she completed the 110 mile swim from Florida to Cuba in conditions that would be described by many as torturous and impossible.

But Nyad was determined to prove these people wrong and her fourth attempt captured hearts around the world as she proved that there is nothing you cannot do when you put your mind to it.
