Due to numerous health benefits, the number of runners, particularly recreational ones, is constantly increasing, which in turn leads to a rise in injuries. Despite a large number of conducted studies, there is still no precise definition of a running-related injury, no data on injury incidence, nor is the mechanism of occurrence fully understood. The aim of this study was to determine the frequency of lower limb injuries among recreational runners, identify the most commonly affected anatomical regions, and connect training characteristics with injury frequency. A total of 253 participants, all members of various running schools, were involved in the study. Overall, 50.2% of recreational runners experienced lower limb injuries, with the knee being the most frequently injured joint and the calf muscles on the back of the leg being the most commonly affected muscle group. Age did not prove to be a significant risk factor for injuries; however, running experience did have an impact, with novice runners showing a higher risk compared to those who have been running for a year or more. There was a statistically significant difference in injury occurrence among those who ran longer distances compared to those with lower mileage. There was no significant difference in injury rates between runners who ran on concrete and those who ran on softer surfaces. Treatment of injuries did not influence the likelihood of injury recurrence. The research highlighted the high frequency of injuries among recreational runners, but further studies are needed to determine a more accurate percentage of injury occurrence and the exact risk factors for their development
