The Great Egg Race was a BBC television series that ran from 1979 to 1986 and featured Brian Cant, Professor Heinz Wolff and Lesley Judd, who joined the series in 1984. It was later revived on BBC Choice and was presented by Johnny Ball.
In a similar vein to the later Channel 4 series Scrapheap Challenge, the show featured teams creating Heath Robinson-esque mechanical creations in an attempt to solve a problem set at the start of the show.
