The man who rolled across America: Gabriel Cordell, Series 1 Episode 10 How to Be Superhuman

Gabriel Cordell became the first person to roll across the United States in a standard wheelchair - giving Rob Pope a lot to chat about with him as they shared tales of their incredible journeys travelling the width of North America.

Supported by a team of volunteers, the 3,100-mile journey from California to New York took 100 days to complete, and saw Gabriel pushing his chair for an average of 30 miles a day.

In the episode, Gabriel lays bare just how torturous this journey this really was, describing everything from the savage terrain he faced in Pennsylvania, as he rolled for 450 miles across the Appalachian Mountains (losing 15 pounds along the way), to the agonising shoulder pain he experienced as he reached mile 650, leaving him temporarily unable to roll his chair another metre.

But, as he reveals to Rob in the episode, it was such a willingness to withstand pain that saw him reach the finish line in his hometown of West Hempstead – and something, he says, we are all capable of. The difference, he says, in somebody accomplishing something extraordinary or not, is simply about overcoming the 'threshold...'

Gabriel also reveals the series of life events that later culminated in him seeking redemption through this Herculean physical and mental challenge – a journey that began 20 years previous when a car accident changed the course of his life forever.
