This week, the team looks at advances in sporting technology. The world 400,000-metre champion, Ros Lamb, demonstrates a new serum (based on caramel-flavoured rocket fuel) which is said to help her to run at up to 3,500 miles per hour. And Ros faces this week's Challenge - can she run the 524 miles from London to Aberdeen in under five minutes? (But it was not foreseen that she would arrive in Scotland half her original size.) We meet two of the clones of the late Sebastian Jackson, the world's most famous football designer. The Invention of the Week is a betting system - based on a machine made of straw and designed by a race-horse. Finally, the team visits the U.S. to investigate the new sport of Gonnis - which is an inspired cross between golf and tennis.
