Check traildamage.com and pick up the funtreks books for Colorado and northern Colorado. Also if you have an iPad or iPhone check the App Store for the PDF Maps app. It's free, and all of the Colorado MVUM maps are in their built in map store for free. If you have android you need to go to the developers site, avenza systems. Anyway these items combined let you look up all the trails in Colorado, then you can plot them in the app, and use the built in GPS to navigate to trail heads. There are tons of trails in Colorado and I am not sure about up near Denver, but I like eagle rock, mt baldy and bull park down here near Colorado Springs. There are other trails too, but I have only run a couple. I also like phantom canyon in the fall when the leaves change.
