Important (and sad) news
This will unfortunately be our last event at the Apex Center. Their programs are expanding, so they can't host events like ours any more. If you love the Apex Center like we do, make sure to attend this one last All-Out event there!
Get ready for the 10th annual Mardi Crawl, where we blend a wonderful winter run with a festive Mardi Gras celebration, Colorado-style! Starting from the award-winning Apex Center 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 is a can't-miss opportunity to experience the best of what Colorado has to offer!
