Trail running is a form of running that takes place on natural terrain, such as dirt paths, hills, and forests. Unlike road running, which is typically done on paved surfaces, trail running offers a more varied and challenging environment. Runners navigate through different elevations, obstacles, and surfaces, which can enhance their strength and endurance. This activity is popular among outdoor enthusiasts and is often associated with ultra-marathons and adventure races. Trail running can be enjoyed by people of all skill levels, from beginners to experienced athletes, and it provides an opportunity to connect with nature while improving physical fitness.
