'Dean's relentless determination to help those who face mental health battles is incredible and admirable - he's a hero to many' Bear Grylls

During sixteen years of service, Dean Stott rose to the top of the Special Boat Service, and took part in some of the most daring operations imaginable. But then, following a horrific parachuting accident, Dean's doctors told him that he would never again perform at the elite level. To put it mildly, Dean disagreed and embarked on a new mission: this time to cycle the Pan-American Highway, a 14,000 mile route passing through some of the world's most dangerous countries.

A passionate mental health campaigner, Dean decided to excel even further by tasking himself with raising a million pounds for charity; and breaking two world records while he was at it. This was his chance to rediscover the tenacity and bravery that led him to become one of the Special Forces elite. However, the final challenge arrived in the unexpected form of an invitation from his old friend Prince Harry - would he make it back in time for the royal wedding, or at all?

Dean Stott is Relentless, and this is his story.
