Prevalence and profile of running-related injuries in the Capricorn running clubs, South Africa
This cross-sectional study of 261 runners in Capricorn, South Africa, found a 59% point prevalence of running-related injuries, predominantly affecting the knee, lower leg, and ankle during training, with soft tissue injuries being most common and suggesting a need for improved load monitoring and asymmetry correction.

Running is one of the most accessible ways humans move, a simple act of putting one foot in front of the other that requires no special equipment or membership fees. People run for many reasons: to clear their minds, to get fit, to compete, or to manage health conditions like heart disease and diabetes. It is an activity enjoyed by young adults seeking leisure and older adults seeking vitality, often taking place on roads, trails, or within organized clubs. However, this freedom comes with a physical cost. The repetitive motion of running places significant stress on the body, and over time, this stress can lead to injuries. These are not just minor scrapes but often deep-seated problems in muscles, joints, and bones that can stop a runner in their tracks. Understanding exactly where and why these injuries happen is crucial for keeping runners healthy, allowing them to continue their activity without pain.
A team of researchers from South Africa decided to investigate this issue within a specific community: the running clubs of the Capricorn district. They wanted to know how common injuries were at a specific moment in time and to understand the profile of the runners getting hurt. To do this, they gathered a group of 261 runners from five different clubs. These were not casual joggers; the group was largely male, well-educated, and employed, with a strong focus on endurance. Most of them were between the ages of 18 and 40, and they were serious about their training, with nearly 90 percent participating in long-distance races like the 42-kilometer marathon or even longer ultra-marathons. Many of them were logging more than 40 kilometers of running every single week.
The researchers asked these runners to fill out detailed questionnaires about their running habits and any injuries they had sustained. The results revealed a striking reality: nearly 60 percent of the runners in the study were currently dealing with an injury. This high rate suggests that for many in this dedicated group, pain is a frequent companion rather than a rare exception. When the researchers looked at when these injuries happened, they found that the vast majority occurred during training sessions rather than during the actual races. While competitions are intense, the sheer volume of time spent training, day after day, week after week, appears to be the primary driver of harm.
The location of the pain told a clear story about which parts of the body are under the most pressure. The knee was the most frequently injured body part, accounting for about 31 percent of all reported injuries. Following the knee were the lower legs and ankles. Interestingly, the data showed a slight imbalance in how the body was being used. More injuries occurred on the left side of the body than the right, particularly in the knees and lower legs. This suggests that many runners might be distributing their weight unevenly, perhaps favoring one leg over the other without realizing it. In terms of the type of damage, the injuries were mostly soft tissue problems, such as strains in the muscles or tears in the ligaments, rather than broken bones. These soft tissue injuries were often linked to overuse, meaning the body was simply asked to do too much, too often, without enough time to recover.
The study also highlighted that while these runners were highly educated and likely aware of health concepts, they still faced significant risks due to their high training loads. The researchers noted that the lack of medical personnel at these training sessions might leave runners without the guidance needed to prevent injuries before they start. The findings point to a need for better management of training volume and a closer look at how runners move. By monitoring how far they run each week, correcting imbalances between the left and right sides of the body, and strengthening the muscles around the knee and lower leg, it may be possible to lower the injury rate. The goal is not to stop running, but to help these dedicated athletes run longer and healthier lives by understanding the specific toll their passion takes on their bodies.
