Back in January, Jo Brand embarked on a seven-day challenge to walk 135 from east to west across the country - and cameras followed her every step of the way. The comedian took on the challenge to inspire all overweight, middle-aged women across the nation - as well as raise money for Sport Relief 2016. Starting out on the Humber Bridge with the aim of reaching Liverpool within seven days, she was tested physically and mentally as she battled extreme cold, gale force winds and torrential rain. But she still found time to share a joke or two with Alan Davies, Lee Mack, Bill Bailey, John Bishop, Gabby Logan and Davina McCall, who joined her on various days.

Documentary following the comedian as he pushes his body and sense of humour to the limit for Sport Relief by taking on the immense challenge of travelling to South Africa to run 27 marathons in 27 days to mark the number of years that his hero Nelson Mandela spent in prison. Cameras chart Eddie's gruelling, uplifting and hilarious journey through baking heat, high roads and hospitals - but can he make it to the final finish line?
