The course for the half marathon at Longmont’s American Heroes Run follows the exact same course that runners in the full marathon, ultra marathon, 5K and relay will run — the one-mile-long loop trail in Rogers Grove Park, which lies just south of the St. Vrain Greenway, west of Longmont’s downtown. The trail is made up of a soft dirt surface, and runners in the half marathon will make 13 loops around the trail to complete their race.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
