I did the Section 16 loop in Colorado Springs in the counter-clockwise direction, starting at the Section 16 parking lot. I ran the entirety of the loop. This was my first time running this route, but the trail is well-marked so I did not have any trouble with navigation. The trail was also fairly busy with with it being a Saturday in summer. It was a beautiful and warm day for a fun run!
