All-Out Polar Prowl 2027

The All-Out Polar Prowl is a winter race at Stenger Sports Complex in Arvada, Colorado, where penguin costumes are part of the event. Held in early January, it includes a half marathon, 10K, and 5K, with virtual options available for participants outside the area. This race is noted as the first Denver-area half marathon of the year. The half marathon, 10K, and 5K each have a four-hour time limit. The courses utilize the Van Bibber Creek Trail, featuring mostly flat terrain with views of Arvada open space and Table Mountain. The course design benefits spectators, with a designated viewing spot allowing them to see half marathoners three times and 5K or 10K runners once before they reach the finish line. All-Out Multicourse Productions is the organizer, and the event benefits Penguins International, also featuring a penguin costume contest.
