The event was born out of the enthusiasm of the newly-formed Knaresborough Round Table in 1966, an organisation looking for a major charity fund-raising push. They came up with the idea of a time-trial in which teams would follow a pre-determined course pushing beds around the town.
It could have been a chariot race, a tug-o-war, a raft race on the river, a soap box derby or any of a hundred other ideas. But they plumped for a bed race, and somehow that unique combination with Knaresborough's almost perpendicular climbs and cobbled streets, the swim across the Nidd and the fancy dress pageant have worked together to make this such a huge and successful community event.
