Adventure running is the sport of running over a variety of surfaces (dirt, road, mountain, sand, snow), generally over long distances, where the racer has to overcome nature. Challenges include river crossing, scrambling, snow, extreme high or low temperatures, and high altitudes.

The dontgetlost.ca Adventure Running series in Ontario has been running for over a decade. It is the oldest and largest series of Adventure Running races in North America.
