Hello,
We have run a similar format for years. We have a fairly small pack, 29 boys this year,but we number each den scout, 1,2,3 etc, 1 stays on lane one, races 2,3,etc on lane two, then 2 goes on lane one, races 1,3,4 etc on lane two. Who ever has the most wins is first, etc. We rarely have a tie, but if we do, they race on both lanes. We have no score board,etc. The adults and boys keep track on there own, and pretty well know who the winners are. This moves along pretty quickly and allows each Cub maximum races for the hard work. We then race each den winner for the leader of the pack.
