Muddy Dash Denver 2026 - Colorado National Speedway

Muddy Dash in Denver is a mud run event on June 20, 2026 at Colorado National Speedway in Denver, CO. The event stages a roughly 5K course with multiple obstacles, mud pits, slides, and about a dozen muddy moments that require running, walking, crawling, wading, slipping, or sliding. Mud pits are described as no deeper than waist level. Timing and competition are not the focus and costumes are permitted.

Event-day activities include a Pre-Party with music, a DJ, dancing, and photo opportunities, and an After-Party at the finish area with a DJ, music, food trucks, and beer. Registration options include a standard package that provides a race bib, finisher medal, and post-race party access, and a VIP package that adds VIP check-in, a tour T-shirt, towel, drawstring bag, sunglasses, a VIP tattoo, and a silicone wristband.

Practical details include a packet pick up scheduled for June 19 at Colorado National Speedway; Race Day packet pickup may be available for a cash fee. On-site bag check is available for a fee paid at the event. Parking may carry a cash charge collected by the venue, with possible card-only handling at some sites.

The event operates a Buy One & Give One program in which a purchased registration funds a donated registration for a local community member, in partnership with several charitable organizations. Visit the organization's website for the most recent information.
