Radzi Chinyanganya, Lindsey Russell and Barney Harwood present a special edition from Baltic Square in Gateshead, Newcastle, where they celebrate three days of events and broadcasts from the North East by launching this year's Blue Peter Sport badge. They are joined on stage by British gymnastic champion Louis Smith and Paralympic gold medallist Hannah Cockroft. The presenters also find out what it takes to make it as a knight when they try their hands as medieval squires.
