About this race
Get ready for the 11th annual Mardi Crawl, where we blend a wonderful winter run with a festive Mardi Gras celebration, Colorado-style! Starting from the amazing Colorado Tap House in Arvada, you can choose your challenge: relatively gentle 5K and 10K courses, or a more challenging half marathon course. All races take you along the acclaimed Ralston Creek Trail, featuring shady, creekside beauty through Arvada's picturesque open spaces and charming golf course communities. Mardi Crawl is also an official BOLDERBoulder Qualifying event! Use your finish time from any distance in this race to qualify for BOLDERBoulder's qualified waves. This event also is part of the endless series with Runapalooza. This is a can't-miss opportunity to experience the best of what Colorado has to offer!
