Once again, the Queen Elizabeth Olympic Park will take up residence in the nation’s living rooms as it hosts this year’s Sport Relief on Friday (March 18).

The BBC TV marathon, compered by stars including John Bishop, Gary Lineker, David Walliams and Claudia Winkleman, will mix fund-raising appeals with celebrity sketches and sporting spectacles.

Highlights will include Newham actor Idris Elba playing to his home crowd as Luther alongside Lenny Henry, Rio Ferdinand, David Haye, Denise Lewis, Cecilia Noble, Louis Smith, Ruth Wilson and Ian Wright.

But the action isn’t just on the small screen. The Olympic venues will be put into use to raise funds for people with tough lives in the Sainsbury’s Sport Relief Games over the weekend. The Aquatic Centre will see a swimathon, the Lee Valley Velopark will host sponsored 25 and 50 mile routes and The Mile will see the Stadium filled with runners.

Entertainment and attractions over the weekend will include a family zone, zip wire, ball pit, Velcro flywall and a chance to have a go at more than 15 sports.

One surprise guest at the Stratford showpiece will be Frank Spencer, back on TV screens after 40 years away.

Michael Crawford is set to reprise his role as the hapless, beret-wearing clown for an audacious stunt-filled sketch that culminates in a chance meeting with cycling legend Sir Bradley Wiggins at the Lee Valley VeloPark.

Crawford said: “I am absolutely thrilled to have been asked to bring Frank back for Sport Relief.”

Sir Bradley said: “I am a huge fan of Michael. It’s an honour to be involved alongside such an icon of British television.”
