ABSTRACT
INTRODUCTION: Mountain running races have grown in popularity in the recent years. Nonetheless, there are few studies on injuries and injury rates. Moreover, these studies have focused on long-distance events such as ultramarathons (>42 km). Therefore, the aim of the present study was to examine the severity, type, and body location of musculoskeletal injuries during 20-42 km mountain running races. In addition, the injury rates in this type of races were examined. METHODS: Data on injuries were collected during 36 mountain running races over 5 consecutive seasons from 2015 to 2019. The participants reported all musculoskeletal injuries on a standardized injury report form. The results were presented as the number of injuries per 1000 h exposure and per 1000 participants. RESULTS: Twenty eight injuries were reported. Most injuries occurred in the ankle (32%) followed by the knee (14%) and foot/toe (11%). The number of injuries represented an overall injury rate of 1.6 injuries per 1000 h running and 5.9 injuries per 1000 runners. The case fatality rate was 0. CONCLUSIONS: The incidence of musculoskeletal injuries during 20-42 km mountain running races is low. In addition, the majority of injuries experienced by runners are minor in nature and located in lower extremities, mainly the ankles.
