This modern version of orienteering is an outdoor challenge that mixes physical exercise with navigation, offering a competitive experience for participants of any skill and fitness level.

That's because exercising while navigating activates the parts of the brain our ancestors used for hunting and gathering, but which are largely dormant now as people rely on GPS to find their way around.
