Castle Creek Triathlon

Castle Creek Triathlon is a desert race at Lake Pleasant Regional Park in Morristown, Arizona. It offers sprint and Olympic triathlon distances, with the Olympic race covering a 1500-meter swim, 24.9-mile bike, and 6.2-mile run. The event also gives athletes other ways to race, including aquabike, duathlon, relays, and a kayak/SUP option, so it is not limited to the standard swim-bike-run format. The course is pitched as tough, with desert terrain and enough climbing to make the bike leg matter; the sprint aquabike alone includes an 800-meter swim, a 22-kilometer bike, and 269 meters of elevation gain. 4 Peaks Racing organizes the event, and Mayo Clinic’s MedMotion group uses it as a community-building athletic outing for students, residents, consultants, allied health professionals, friends, and families. Relay teams are especially popular, which makes the race accessible to people who want the event experience without doing every leg themselves.
