"Running" is really a stretch. I run a kilometer/klick/0.62 miles, re-orient, run, re-orient, and so on. With radio as I get closer and closer it becomes harder and harder and visual search is required, lots of triangulation with the radio. Old fashioned orienteering is similar, but replace the radio orientation with pulling out a map & compass, re-plot, stash, and run. Some do longer, some do shorter distances. When I write "run" I mean I try to move as fast as possible. I can run on flat ground, but sometimes hillsides is just crawling, creeks will slow me down, swamps & bogs are the worst. I do not know what country your response is based on, but there are lot of national parks in the world, and most parks will work with and even help organize an event. This topic came up in discussions and the general consensus was that if it is completely denied, people will do it in clandestine fashion. If, on the other hand parks work with the run organizers, it not only makes sure rules can be established (e.g., no off trail, restricted zones, zones where only one path allowed, timing) and the park is promoted for general public. A win-win-win-win ;)
