The Colorado Outward Bound Relay, a 170-mile team relay race, is the premier team event designed for athletes of all abilities in Colorado. The majority of teams have 10 participants each, with each runner responsible for three segments of the course. The average distance for each leg is five miles. This event was created for both casual and competitive runners, in support of building a positive team atmosphere and a 24-hour adventure through beautiful Colorado.
Ultra runners are responsible for running one segment of the race.
Beginning in Idaho Springs, CO, the course makes four ascents through mountain passes, crosses through several aspen groves and meadows and follows sections of the Colorado Trail, while winding through dirt and paved roads and paths.
