Hop, Step, and Jump
This is a change from ordinary racing. The competitors, instead of running against each other, see which can cover the most distance in a hop, a step, and a jump, or, say, three hops, three steps, and three jumps. It needs an umpire to watch very carefully that the step begins exactly where the hop left off and the jump where the step finished.
Follow-My-Leader
This needs no explaining. It is nearly always good fun for a while, and particularly so if the leader has original ideas.
