Muddy Dash | Denver 2026

Prepare for an unforgettable adventure at the Muddy Dash | Denver 2026, a 5K race promising messy mayhem and exhilarating obstacles on June 20, 2026, at the Colorado National Speedway in Dacono, CO. This isn't your average run; it's an experience designed for pure fun, not fierce competition. You and your team can expect to navigate "a few miles of fun" through rough terrain, tackling "about a dozen Muddy Moments" that will have you running, walking, crawling, wading, slipping, and sliding through a variety of challenging obstacles. Typical race day conditions in late June bring highs around 88°F and lows around 54°F, with only a 6% chance of precipitation, ensuring prime muddy conditions.

The Muddy Dash course features an array of creative challenges, including mud pits that are never deeper than waist-deep, so there's no need to worry about swimming. Prepare to encounter walls, ropes, monkey bars, and even rock formations, culminating in a triumphant finish line where foam cannons will blast you clean. This untimed event encourages participants to embrace the filth, with costumes highly welcomed to add to the festive atmosphere. Whether you race solo or with friends and family, the rolling starts ensure a relaxed beginning, allowing everyone to spread out and enjoy the experience at their own pace.

Beyond the course, the Muddy Dash | Denver extends the excitement with a lively post-race celebration festival. Attendees can enjoy food and beer vendors, live music, giveaways, and photo opportunities to capture their muddy achievements. Water-only aid stations are strategically placed mid-course and at the finish line to keep participants hydrated. A portion of the proceeds from Muddy Dash events supports research, funding, and treatment for families battling childhood cancer and terminal illness, adding a meaningful cause to your muddy adventure.
