    Breathe in the thin air and bold ambition of the "Mile High City," a destination where the Rocky Mountains serve as a daily reminder to climb higher. Denver is the ultimate playground for the outdoor-obsessed, home to a culture that prioritizes health, mountain-fresh air, and a rugged sense of adventure. It is a city that respects the climb and rewards the effort, making it a natural home for the DEKA community to converge and conquer.

    This exclusive one-day event takes over the Gaylord Rockies Resort & Convention Center, a premier rustic-inspired resort with sweeping views of the Front Range. The one-day schedule is packed with intensity, leading off with the DEKA FIT Ultra for those looking to maximize their lap count. Individual athletes will then hit the floor for the Elite and Age Group heats, along with the weighted challenge of the Ruck waves. The day concludes with the high-speed coordination of 2-Person Teams, giving you the chance to leave it all on the floor in the shadow of the Rockies.

    ATHLETE JUDGE PROGRAM

    DEKA is truly a fitness movement we all created together. To ensure a professionally judged racing experience for all athletes, we ask all registered athletes to participate in the DEKA Athlete Judge Program at DEKA FIT events.

    How it works:

    If you are registered to race this event, please use the Denver DEKA FIT Athlete Judge Sign-up Form to select your preferred Athlete Judge time.

    Within 1 hour of finishing your race (or anytime before your race), make your way to the Athlete Judge check-in area at Zone 1 to begin your 60 minute volunteer judging time.

    We can’t thank you enough for your support as we continue our mission of creating an epic opportunity for ALL levels to celebrate fitness together.
