I did my first real trail run today on a 1 mile singletrack (did two rounds) that was rocky, hilly, rutty, wet, earthy, buggy, spiderwebby, and a heck of a lot of fun! I love my trail shoes - they really stick! It all felt very primeval and sweaty (well, the 85 degree 90 pct humidity probably helped with that.) I totally have to do more runs on the trail. So much fun!
