For those who insist on running with iPods, here is a good race idea. Come up with several courses with the same starting and ending points. Runners randomly download course directions to their iPod. When the race starts, you hit play, and follow the directions. The Kansas City Trail Nerds recently did this with three 3.1 mile courses of different difficulty. Another option would be multiple courses with the same average time and different lengths. Or you could randomly hand out maps, but then you are on your way to orienteering.
