The Duel in the Desert Duathlon is a run-bike-run race sponsored by the Mt. Bacehlor Rotary in Bend, Oregon. Contestants - most competing as individuals but some as two- or three-person teams - start five kilometers run on roads and dirt trails.
Runners loop back to the start, where they change shoes and strap on cycling helmets for the bike stage. Racers choose between a road-bike course (18 miles out and back) and an off-road course for mountain bikes (about 12 miles, mostly on single-track trails.) Produced by Scott Nelson Productions, Inc.
Riders returned to the start area for the transition to the final stage of the race, a repeat trip on foot around the running course.
