I am avid watcher of and devoted participant in adventure racing. The expedition races I follow (monitoring progress on an online map) are three- to six-day races that occur all over the world. In an adventure race, racers plot their path to checkpoints across a course that spans 300-plus miles (usually 50-100 miles a day) while mountain biking, rock climbing, running rapids, trekking, and more.
