Track and field, cross-country, and marathon/ultramarathon running are among the world’s oldest sports. Track and field originated in ancient Greece, where the first recorded Olympic Games had been held in 776 BCE. Running sports include track and field, cross-country, marathon, and ultramarathon running. Dermatoses among running athletes vary based on event specialty based on differences in equipment and biomechanics. Contact dermatitis results from equipment field event athletes use and clothes or tape runners use. Environmental exposure to extreme heat, cold, and ultraviolet radiation is a major cause of dermatoses among running athletes. Friction and pressure secondary to running shoes, clothes, and the biomechanics of running result in dermatoses among running athletes. Trauma from the repetitive movements of running leads to distinct skin and nail manifestations. While running sports aren’t contact sports, these athletes are still at risk for developing infections. Prevention at the microscopic and macroscopic levels is crucial to optimize skin health among running athletes.
