I love trail running, so I’m surprised it took me so long to find RunTrails.org. The site offers a ton of useful resources for people who practice this sport, and for those who are looking to get started. I’ve been getting plenty of use of their lists of running trails by states, which allows me to find places I should visit when I’m on the road. And their trail running tips have been useful in the past as well. Most of it is stuff I already knew, but it’s good to review the basics, and their guides are useful when I’m helping beginners get started.
