The Experience
The 11th annual Mardi Crawl combines a scenic winter run with a lively Mardi Gras celebration, starting from the Colorado Tap House in Arvada. Runners can choose from a gentle 5K or 10K, or the more challenging half marathon course that winds along the Ralston Creek Trail. The route offers shady, creekside beauty through Arvada's open spaces and golf course communities, with a Colorado-style twist.
With a median field of about 92 finishers, this is an intimate event where the small-town, local-community vibe shines. The Mardi Gras theme carries through to the finish, with a festive atmosphere and post-race celebration. As an official BOLDERBoulder qualifier, the half marathon offers a chance to earn a competitive wave start for that iconic race. Expect rolling terrain and a course that's well-supported but low-key, perfect for those seeking a unique, community-driven race day.
