About this race
Join us for the 14th annual Polar Prowl at the Stenger Sports Complex in Arvada, CO! As the first Denver-area half marathon of the year, this event features 5K, 10K, and half marathon courses that meander along the Van Bibber Creek Trail, offering breathtaking views of Arvada's open spaces and Table Mountain. Because the courses are relatively flat, it is the perfect opportunity to chase a personal record or secure a qualifying time for the BOLDERBoulder. We are proud to support Penguins International with this event, and we invite you to join our penguin costume contest. The layout is incredibly spectator-friendly, featuring a viewing area just a short walk from the venue where fans can cheer on half marathoners three times and 5K or 10K athletes once before they hit the finish line.
