Embark on a memorable trail running adventure at the Barr Lake 30K and 15K, set for June 13, 2026, in Brighton, CO. This popular event, celebrating its eighth year, is renowned as one of Colorado's flattest and fastest courses, offering an exceptional opportunity for personal bests or a welcoming introduction to trail racing. Runners will navigate a scenic looped course of 100% dirt terrain around the expansive Barr Lake, enjoying continuous, uninterrupted views of the glistening water and the majestic Colorado Front Range. Beyond the stunning vistas, the course winds through areas rich in cottonwoods and marshes, providing ample opportunities to spot some of the over 350 bird species, including magnificent Bald Eagles, that call Barr Lake State Park home. With less than 100 feet of elevation gain per loop, this non-technical trail is designed for enjoyable, consistent pacing, though some sections may be exposed to the sun.

The race offers distances beyond the namesake 30K and 15K, including a 50K, Half Marathon (13.1M), and 5K, ensuring a challenge for every runner. Each loop is well-supported with multiple aid stations to keep you fueled, and for longer distances, drop bags are conveniently located at the start/finish area near the Nature Center. Typical race day conditions in mid-June feature pleasant temperatures with highs around 86F and lows around 52F, and a minimal 6% chance of precipitation. Whether you're chasing a new record or seeking a beautiful, accessible trail experience with abundant wildlife and stunning natural scenery, the Barr Lake Trail Race promises an unforgettable day on the trails.
