A 10K race is a long-distance road running competition over a distance of ten kilometers (6.2 miles) . It is one of the most common types of road running events, alongside the shorter 5K and longer half marathon and marathon. The popularity of 10K races lies in the fact that, for most adults, the 10K distance is long enough to represent a challenge but short enough to remain accessible for an untrained runner. Most popular 10K races are an annual fixture in a city or area and typically incorporate an element of charity running, where participants raise funds for a cause based upon their completion of the course. The average time to complete a 10K race is 50-70 minutes, but this can vary depending on individual factors such as age, cardiovascular fitness, and musculoskeletal health.
