Trail running is a form of running that takes place on natural terrain, such as dirt paths, hills, and forests, rather than on paved roads. It often involves varying elevations and surfaces, which can include rocks, roots, and streams. This type of running allows participants to connect with nature while enjoying the physical benefits of aerobic exercise. Trail running can be done solo or in groups and is popular among outdoor enthusiasts. It requires specific gear, such as trail running shoes, which provide better grip and support on uneven surfaces. Many runners appreciate the challenge and beauty of scenic trails in different environments.
