Louisville Trail Race 10K

2026

The Louisville Trail Race 10K takes place in November in Louisville, Colorado, offering an out-and-back course that covers 6.3 miles on dirt trails. With 285 feet of elevation gain and a 2.75-hour time limit, this race provides a manageable challenge for runners looking to experience Colorado's Front Range without committing to a longer distance. The course features two notable climbs at miles 0.8 and 4.7, giving runners views of the Flatirons and surrounding foothills. Since it's an out-and-back format, you'll tackle the main hill early in the race and again on the return journey. The route stays on dirt trails throughout, winding through the Louisville area with the backdrop of Colorado's front range mountains. Three aid stations provide support along the way, including water-only stops at miles 1.1 and 5.2. Runners comfortable with modest climbing and dirt trail surfaces will find this race approachable, while the November timing means cooler temperatures and potential weather variability typical of Colorado's late fall. The family-friendly atmosphere and post-race festivities make it appealing for those wanting a community-focused trail experience rather than a hardcore suffer-fest.
