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.
