Embark on a scenic journey through Colorado's Carbon Valley at the Half Marathon, 5K, and 1 Mile Fun Run on Saturday, May 9, 2026, in Firestone, CO. This charming small-town race, renowned for its excellent organization and community feel, offers a diverse course that promises both challenge and breathtaking views. Runners will traverse a unique blend of manicured trail systems, dirt paths, bridges, and rural roads, soaking in spectacular vistas of the Rocky Mountains from start to finish.

The certified half marathon route guides participants through highlights like Firestone's Central Park, the Firestone Trail, and around Frederick's picturesque Milevac Lake. While the course features a fantastic two-mile downhill finish, runners should be prepared for varying terrain, including sections of low gravel farm road and potentially uneven ground in certain areas. Aid stations are well-stocked, offering water, electrolyte drinks, snacks, and basic first aid, with multiple opportunities for hydration on the half marathon course. Typical race day conditions in early May feature pleasant highs around 67°F and lows around 40°F, with a low chance of precipitation, though runners should be mindful of the altitude if coming from sea level.

Beyond the personal challenge, participating in the Carbon Valley Half Marathon supports a vital cause, with proceeds benefiting Autism Research through Children's Hospital Colorado. Every Half Marathon and 5K participant receives a tech t-shirt, finisher's medal, and goodie bag, with a celebratory atmosphere awaiting at the finish line, complete with post-race snacks and even a complimentary beer. The start and finish lines are conveniently located at the Firestone Regional Sports Complex, ensuring a smooth and enjoyable race day experience.
