Adventure Racing

Adventure racing (also called expedition racing) is typically a multi-disciplinary team sport involving navigation over an unmarked wilderness course with races extending anywhere from two hours up to two weeks in length. (What Is Adventure Racing Video) Some races offer solo competition as well. The principle disciplines in adventure racing include trekking, mountain biking, and paddling although races can incorporate a multitude of other disciplines including climbing, abseiling, horse riding, skiing and white water rafting. Teams generally vary in gender mix and in size from two to five competitors, however the premier format is considered to be mixed gender teams of four racers. There is typically no suspension of the clock during races, irrespective of length; elapsed competition time runs concurrently with real time, and competitors must choose if or when to rest.

The roots of adventure racing are deep and people debate the origin of the modern adventure race. Some point to the two-day Karrimor International Mountain Marathon, first held in 1968 as the birth of modern adventure racing. The Karrimor Marathon required two-person teams to traverse mountainous terrain while carrying all the supplies required to support themselves through the double-length marathon run.

In 1980, the Alpine Ironman was held in New Zealand. Individual competitors ran, paddled and skied to a distant finish line. Later that year, the Alpine Ironman's creator, Robin Judkins launched the better-known Coast to Coast race, which involved most of the elements of modern adventure racing: trail running, cycling and paddling. Independently, a North American race, the Alaska Mountain Wilderness Classic debuted in 1982 and involved six days of unsupported wilderness racing (carry all food and equipment, no roads, no support) over a 150-mile course. It continues today, changing courses every 3 years.
