Sports Medicine and Arthroscopy Review: December 2012 - Volume 20 - Issue 4 - p 206-213 doi: 10.1097/JSA.0b013e31825ca79f Buy Metrics Abstract The running portion of the triathlon represents the final leg of the competition and, by some reports, the most important part in determining a triathlete’s overall success. Although most triathletes spend most of their training time on cycling, running injuries are the most common injuries encountered. Common causes of running injuries include overuse, lack of rest, and activities that aggravate biomechanical predisposers of specific injuries. We discuss the running-associated injuries in the hip, knee, lower leg, ankle, and foot of the triathlete, and the causes, presentation, evaluation, and treatment of each. © 2012 Lippincott Williams & Wilkins, Inc.
