I ran road when I was a kid, but for me now, trails are like getting away from the world. If you are a road-runner, you are dodging cars and whatnot, so for me, trail running is a release. When I get up in the morning and I go running, it's therapeutic. Especially in the mountains: the smell, the nature, the wildlife. It's so much nicer. It's easier on the body, since its softer.
