Be a part of history - this is the longest continuously run road race in Colorado!  Since 1978, the Narrow Gauge 10 Mile Run and 5k have 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 The Fort Lewis College and Durango High School Track and Cross Country Teams as well as The Liberty School and Animas High School. Parents can join in on the Kids' Fun Run. One of the most exciting weekends of the year; Iron Horse/Memorial Day Weekend.
