He has always pushed himself to do extraordinary things. In 1986, he led a British/Indian police expedition to summit unclimbed peaks in the Himalayas.
In 2004, John became the oldest British person to row across the Atlantic unsupported and spent the next decade seeing how his body and mind could cope in extreme situations, from serial desert marathons at the notorious MDS to walking to the North Pole.
As a senior police officer in London he was brought in to command a police division in Stoke Newington, then a notoriously dangerous part of the city, throughout the riots of the mid-1980s
He learned much about leadership during this period and was invited to run leadership development programmes for senior police officers at the National Police Staff College in Hampshire.
In 1995, at the age of 50, he was starting to get restless and left the police service to set up his own consultancy, training business leaders in the private sector.
At the time of writing this book, John splits his time between coaching senior business managers through his consultancy, Tiger Teams, and running wilderness survival programmes on remote Scottish islands for inner-city youth leaders working with violent gangs.
He is well known for his powerful talks in which he inspires people to take on challenges in their own lives that may at first seem impossible – a subject dear to his heart.
His passion is to help senior leaders fire up their teams with a spirit of adventure to take on Game Changing challenges and make the impossible possible.
