The hilarious trials and tribulations of stand-up comedian Paul Tonkinson as he attempts to beat the much lauded 3-hour mark at the London Marathon. With a supporting cast of fellow comedians, this is a warmly written and wonderfully honest adventure-through-sport that will both entertain and inspire.

Along the way, we are introduced to the characters helping Paul with his quest. Celebrity names such as Bryony Gordon, Russell Howard, Roisin Conaty and Vassos Alexander pop up with wit and wisdom, alongside an alpine adventure to the Mayr Clinic with Michael McIntyre that pushes Paul to the limit. And not forgetting the 'words of wisdom' and derision from Paul's anti-running friend, Richard.
