Nielson Two Mile Challenge - Colorado Springs, Colorado - Running

The Nielson Two Mile Challenge is a Running race in Colorado Springs, Colorado consisting of a 2 Mile Trail Run.

The course will change for the Nielson Challenge. The first mile will be the loop portion, run in a counter clock-wise direction. The second mile will be the out-n-back section, going south for a 1/2 mile, and then north for a 1/2 mile. This is being done to alleviate the congestion that has been experienced along the narrow section of trail near the southern turnaround. As the numbers have grown for the Nielson, some runners have been getting squeezed along the narrow section after they make the turn and run upstream against the flow of oncoming runners.
