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.
