Mel Giedroyc joins David on a two-wheeled trip along the Northumberland coast, ending up at the tidal Holy Island, but crossing rivers on a bicycle proves tougher than it looks. Along the way, they explore stunning coastal views peppered with castles and ancient ruins and take time out to make portraits of each other out of seaweed.
