Start (of course) in London – but where will you end up?

Draw two long parallel lines with chalk (do the whole street if you are feeling energetic!) about a metre apart. Then draw lines across to make a ‘train track’. Each player throws a stone as far down the tracks as they can, ensuring that it lands inside a space. They can then move the stone on from there but only by kicking it along while hopping, using the same foot. If the stone goes outside the lines, or they put their foot down, they must stop and the next player goes.

First one to Paris (or Istanbul, or Cairo or…. ) wins!
