Sure! :-) As I've mentioned previously, my main hobby/sport is orienteering, where you navigate (i.e. run if possible!) from a starting point, via a number of controls marked on a (paper) map, to the finish. Individual start, fastest time wins, no fancy gear at all: Just the map with the marked course and a regular compass.
