A Run for Trails

The Pikes Peak Road Runners American Discovery Trail Marathon supports PPRR and the Trails and Open Space Coalition. The scenic course along paved and dirt trails is about as fast and flat as you can find in Colorado. All proceeds directly benefit local trails and local non-profits dedicated to trail stewardship and community running events in Colorado Springs.

The ADT Marathon is recognized as a premier race event by local and out-of-state runners, and is proud to celebrate its 16th year in 2016! Join over 1,000 runners competing in the marathon, relay, half marathon, or 10K races with new and improved courses for 2016, with the start and finish at America the Beautiful Park in downtown Colorado Springs.

Runners will be treated to flat, fast courses, a tech tee, finisher medal, and a fun Labor Day post-race party. Plus, the outstanding volunteers and course support you’ve come to expect from Pikes Peak Road Runners.

We are also honored to announce that the American Discovery Trail Marathon and Half Marathon have been selected as the 2016 State Championship Races for the Road Runners Club of America.

Come for the scenic, speedy course, come back for the amazing volunteers, and stay for the live music, crowd-pleasing spread and beer garden at the post-race party in the heart of Colorado Springs.

Comments from runners:

"We have done years of organized runs and both agreed this run had the most of everything any runner could seek ~ from bathrooms, to water, to friendly volunteers, to awards, beer, great shirts, wonderful singing of the anthem, 'perfect running weather'! (ordered up from Mother Nature), great views, and lots of delicious free food at the end.  I'd say a perfect '10' in every way!!" L. Meillier

"America the Beautiful" was written in the 1890s after a hike up Pike's Peak. For anybody doing his race and especially us flatlanders - you can see how the author was inspired. Beautiful day, beautiful course. I had some cramping issues the last four miles, but just about the time I'd feel bad, I'd simply look at the scenery and start grinning." T.S., Indianapolis (posted on

"Just wanted to say thank you for doing such a great job with the race. I had a spectacular time and so enjoyed the scenery and people. Everything went beautifully:) Thanks, again, for all of your hard work and putting in an order for such a beautiful day. Also, the water sculpture at the park is a wonderful addition to the experience! Really helped to put my legs in it after the race!" S. Nies
