The Sun Herald Sydney City-2-Surf Fun Run - Historical Injury Patterns and Factors Influencing Injury Type and Frequency

With nearly 80,000 entrants, the Sydney City-2-Surf Fun Run is the world’s largest annual run. The authors examined injury patterns during the event from 2010-2016 and found significant relationships between the number of heat exhaustion patients and temperature at noon. Musculoskeletal injuries were more likely where the course was steepest, and “heartbreak hill” was the scene of a cluster of cardiovascular events. These findings can help others plan for similar events.
