Every January in Arvada, Colorado, All‑Out Multicourse Productions brings festive energy to winter running with the Polar Prowl—featuring 5K, 10K, and USATF‑certified half marathon distances. Now in its 13th year, this event is a well-loved fixture on the winter race calendar.
The half marathon begins at 9:00 AM MST from Stenger Soccer Complex and follows a double out-and-back route along the scenic Van Bibber Creek Trail. With minimal elevation (~mostly flat), concrete/smooth trail surfaces, and twelve fueling stations spaced every ~1.2 miles, it’s a fast and supportive course designed for PRs—even in winter conditions.
This race is equally celebrated for its logistics: ample aid (water, electrolytes, gels), portable restrooms, and a post-race spread featuring breakfast tacos, fruit, bagels, and chocolate milk for all finishers.
It’s a community-centric, winter-warm event—walker- and dog-friendly, with relaxed pacing but serious volunteer support. A Reddit report from 2018 mentioned icy sections near the start-line but praised the trail itself and scenic backdrop, including Rocky Mountain views.
Whether you’re aiming for a cold-weather PR or just looking to embrace the new year with a festive run, the Polar Prowl mixes performance, practicality, and playful winter spirit.
