The lack of studies on Crossfit® injuries in Spain, motivates the realization of this descriptive, observational and retrospective epidemiological study, analyzing the incidence and characteristics of injuries suffered by Crossfit® competitors and non-competitors.The injuries suffered by 434 athletes between from January 1^st to December 31^st 2019 were recorded. We collected data on the number of injuries, the most frequent injuries, their distribution, type, location, the moment at which these occurred and the cause of the injuries affecting the musculoeskeletal system. We found that the injury rate in this population was 3,48 injuries per 1000 hours of risk. The shoulder and lumbar area were the most frequently injured anatomical areas, with muscle and tendon being the most common seat tissue of injuries. Powerlifting was the most damaging activity.
