Robson is joined by his brother David and uncle Matheson for a two-day break on a canal boat in the Yorkshire Dales.
Taking the cross-country route, they marvel at the Ribblehead Viaduct and learn to navigate the Leeds-Liverpool canal, with its locks and swing bridges, in a downpour. After a spot of fishing and family competition, Robson lines up an abseiling challenge for former scaffolder David at the famous Cow and Calf.
