This is great loop for running, even better, you can string it together by starting at Wonderland lake and taking the Foothills Trail over to Eagle, then take Eagle out to 55th(the Boulder Reservoir road) head south to Jay rd. and then west through the NoBo Neighborhoods back to Wonderland Lake. I think it's like 12 - 13 ish miles.

Moderate trail without much elevation gain and great views of the foothills.

Decent walking trail. Portion of trail takes you through cow pasture. Lots of dog, horse and cow poop on trail. EASY walk if you just want to stretch your legs.
