Summary: Former world champion athlete Liz McColgan, and the nation's favourite football pundit Chick Young are our final pair in the series. A single mother of five, Liz's hectic lifestyle means she struggles to find the time to do the things she knows she should be doing but currently cannot. Between getting four of the children off to school in the morning, looking after her gymnasium business, and her coaching sessions at Hawkhill Harriers in Dundee, she barely has a minute to herself. As a result, controlling the household budget is not a priority. Chick is an unreconstructed petrol-head. He runs a car, a motorbike and a boat. Both Liz and Chick live in substantial Victorian stone properties, which are notoriously difficult to heat efficiently and they could do with some advice on how to reduce their large domestic fuel bills
