Frequently asked questions
What is trail running?▾
Trail running takes place on unpaved surfaces like dirt paths, mountain trails, and forest roads. Distances range from 5K to 100+ miles. Trail running emphasizes scenery, elevation, and technical terrain over pace.
What shoes do I need for trail running?▾
Trail running shoes have aggressive lugs for traction, rock plates for protection, and a more durable outsole than road shoes. Popular brands include Hoka, Salomon, and Altra. Choose shoes based on your local terrain.
How is trail running different from road running?▾
Trail running involves more elevation change, uneven footing, and slower paces than road running. Expect to run 20-40% slower on trails compared to roads. The focus shifts from pace per mile to effort and time on feet.
