Colorado is known for being an outdoor mecca of sorts. One of the most popular outdoor activities is trail running. With miles and miles of trails throughout the state, it is hard to choose. We have teamed up with the Trail Run Project to provide a map of trails in Colorado. You can search for your area or favorites on the map below. Then you can see a detailed description and a map of the trail. You can also create and account and add your favorite trails if you don’t see them listed. Have fun and happy trail running!
