David outlasts the previous record of 16 minutes, 32 seconds...and keeps going! Finally, at 17 minutes, 4.4 seconds, he breaks the surface of the water and takes his first breath as a Guinness World Record holder. His lifelong dream has finally come true.
Although the experience was intense, David emerges safely and says he feels great. "I feel slightly emotional. I feel good about it and pretty happy," he says. "I can't believe that I did that."
At one point, he says he had a moment of doubt when he noticed his heart rate was higher than normal. "I was going to fight hard, but I was not sure," he says. "I'd never done it with such a high heart rate."
