Blue Peter welcomes the 36th presenter of the show, Lindsey Russell, who was chosen by CBBC's viewers. Lindsey's first live studio show sees her jumping in at the deep end - literally - as she jumps from a 10 metre high diving board in preparation for a much bigger challenge - jumping off Worthing Pier as part of the Worthing Bird Man event. See if she gets off to a flying start! There's also the chance to catch the first part of Helen Skelton's latest feat of endurance - a gruelling Royal Marine challenge that will push her to the limits!
