Longmont Half Marathon & 5K

Thursday, July 4, 2019 • Longmont, CO • Course Map

Lying just east of the front range of the Rocky Mountains and Longs Peak, one of Colorado’s many mountains that peak above 14,000 feet, Longmont plays host to this race on the 4th of July every year, along an out-and-back course that takes runners along a trail system that winds through several of the city’s parks.


Runners first make their way through Flanders and McIntosh Park, all the way around to the opposite side of the lake, where they turn off the trail at Lakeshore Drive and head through the residential neighborhoods just south of the lake.

Turns on 17th Avenue and Airport Road are followed by a long straightaway stretch down Airport for the next few miles, until about halfway between the mile 4 and 5 markers, where runners turn left and head east into the Golden Ponds Nature & Park Area.

This 94-acre park and its four large ponds are a popular wildlife and bird-watching spot, and runners will trek through the park toward the St. Vrain Greenway trail, which winds alongside the St. Vrain Creek for five miles diagonally through the city and is part of the Front Range Trail, a running, walking and biking trail system that is eventually planned to stretch from Wyoming to New Mexico.

The race route keeps runners on the St. Vrain trail for about the next four miles, turning off when runners reach 119th Street and then turn again onto Quicksilver Road. The last couple of miles bring runners back onto the trail and then into Sandstone Ranch Park, where the race finish line lies.
