My promise is that there is very little superficial chit-chat or waffle in this nearly two hour conversation - it’s a high performance masterclass, relevant for sport and life, delivered by someone who has been there, failed and succeeded, against the odds.

Mark is one of the world's best Big Wave surfers. It’s a sport that’s reserved for only a special few who surf 30-50 foot waves that can seriously injure or drown the warriors that ride them. Yet Mark is not a ‘natural' fit for this sport. He is no adrenaline junkie or hell-man; is certainly not fearless and is not particularly powerfully built.

He ’suddenly’ appeared on the Big Wave surfing stage when he rode a wave so treacherous that other more experienced surfers wouldn’t. Following this success he had to figure a way to not only survive on this stage, but to become the world's best.

He learned the hard way. Extreme highs were followed by extreme lows. A string of global awards were followed by tearing every structure in his shoulder whilst a series of 40 foot waves crashed down on his broken body. Weeks after recovering from this year-long injury, he suffered an even worse one. This time he was one hour away from losing his leg - an injury which left him with permanent damage that should have ended his surfing career.

Against all odds, and with no movement or feeling in his lower leg, Mark is back surfing Big Waves.

He has an insatiable hunger for learning, which helped him survive and then thrive in the world of Big Wave surfing. Mark is a sought-after and captivating public speaker on the subjects of fear, resilience, adversity and high performance.

With openness, honesty and sometimes vulnerably, he shares all this and more.
