From British Orienteering:

Orienteering is a challenging outdoor adventure sport that exercises both the mind and the body. The aim is to navigate in sequence between control points marked on a unique orienteering map and decide the best route to complete the course in the quickest time. It does not matter how young, old or fit you are, as you can run, walk or jog the course and progress at your own pace.

Orienteering can take place anywhere from remote forest and countryside to urban parks and school playgrounds. It’s a great sport for runners, joggers and walkers who want to improve their navigation skills or for anyone who loves the outdoors. Orienteering - The adventure sport for all.
