The Narrow Gauge Races

Race Info

The Narrow Gauge Races is on Sunday May 24, 2026. It includes the following events: The Narrow Gauge 10 Mile, The Narrow Gauge 5K, and The Narrow Gauge 1-Mile Kids' Dash.

Be a part of history -- this is the longest continuously run road race in Colorado! Since 1978, the Narrow Gauge 10 Mile Run has been one of Durango's oldest Memorial Day traditions. This year, we're back at beautiful Santa Rita Park along the Animas River. We are excited to announce our beneficiaries of the races this year are Big Brothers Big Sisters of San Juan County, The Ft Lewis College and Durango High School Track and Cross Country Teams as well as The Liberty School.

The 10 Miler will climb from the river trail up to Fort Lewis College with the best views of the La Plata Mountains then past Hillcrest Golf course. It will be a mix of sidewalk, dirt and paved road as well as singletrack trails The descent will take runners back to the east side of the Animas River to the Rivergate Bridge then north along the river trail back to the start/finish. For a change of pace the 5K race heads south from Santa Rita Park crosses over the Animas River and continues south along the eastern banks of the river on a dirt trail that will take runners to the Rivergate community. After ascending thru the heart of Rivergate up to Sawmill Road ,runners will descend back down to the river and cross over the bridge to the Animas River Trail and head north back to Santa Rita Park on the sidewalk. Parents can join in on the Kids' Fun Run.

One of the most exciting weekends of the year; Iron Horse/Memorial Day Weekend. A great race for those who want to make it a biathlon weekend or who are cheering on the bikers on Saturday and want their own footrace on Sunday. We even have a few racers who are doing all three: Narrow Horse 1500 Meter Swim on Friday, The Iron Horse Bike Race on Saturday and a Narrow Gauge Road Race on Sunday!

There will be music, food, a sweet custom 16oz can glass for all 10 mile and 5k racers. There are Age Group Awards! Top 3 in each age group in the 10 Mile and top 2 in each age group in the 5K will be receiving a gift from a local Durango business.
