In this brand new Come Dine with Me celebrity special, four Olympians battle it out to win a £1000 cash prize for charity. Former world champion javelin thrower Fatima Whitbread kicks off the week focused and totally prepared, but with a light and healthy meal for her guests. Just as well, considering she quickly has them all competing in her very own sports day in her back garden! Record-breaking, barefoot runner Zola Budd adds a South African touch to the week with her family-inspired recipes. High-jump champion Dalton Grant reaches new lows with a limbo dancing contest during a Caribbean-themed night. And last to go for gold is 400m hurdles gold medallist Kriss Akabusi who, reliving a past career in the army, provides a military drill instructor to whip his guests into shape.
