Discover the exhilarating Rock Hawk Trail Races, set against the stunning backdrop of Castle Rock, Colorado, on August 29, 2026. This highly regarded event offers a range of distances including a 50K, 25K, 10K, and 5K, providing a challenge for every level of trail runner. The courses wind through the gorgeous, thrilling, and rolling trails of Philip S. Miller Park and the Ridgeline Trail systems. Expect non-technical singletrack and multiuse trails that are both flowy and cruisy, with some twisty turns through scrub oak and vegetation. While not overly technical, certain sections present "chunky" terrain where attention to foot placement is key, all while soaking up amazing views of the valley. The 50K boasts 3,325 feet of elevation gain, the 25K has 1,667 feet, the 10K features 744 feet, and the 5K climbs 342 feet, all classified as hilly. Runners will reach a maximum elevation of around 6,635 feet, so preparing for the altitude is advised.

The Rock Hawk races are celebrated as an excellent choice for both first-time and veteran trail runners, offering a perfect test for those training for longer summer events. Aid stations are conveniently located cup-free stops, providing water, electrolyte drink (Tailwind), sweet and salty snacks, and fruit. Participants can leave a weather-sealed drop bag at the start/finish line in Philip S. Miller Park, which also serves as the hub for bib pickup and crew support. Typical race day conditions in late August bring highs around 83°F and lows near 53°F, with a minimal 6% chance of precipitation, creating an ideal setting for a memorable day on the trails. A portion of the race proceeds benefits the open spaces and trails of Castle Rock and partner charities.
