Course and event features
The in-person course runs on the Van Bibber Creek Trail. The route is described as relatively flat and spectator-friendly, with views of Arvada open spaces and Table Mountain. The event includes a penguin costume contest and introduces new art and race swag, including a new banner, finish line arch, updated race shirt and medal, and alumni brag tags. Dog finisher tags will be available, and extra medals may be offered for purchase. Overall winners are eligible for cash prizes and may receive prizes from partners.
Charity, volunteers, and partners
The event benefits Penguins International, a Denver-based 501(c)(3) nonprofit supporting penguin conservation, education, and research. Projects mentioned include an incubator project for Endangered African Penguins in South Africa, nest boxes for Humboldt Penguins in South America, and funding Emperor Penguin research using SPLASH GPS tracking tags. Organizers report a critical need for course volunteers; volunteer shifts may earn bonus credit, free race entries, or trigger a donation to Penguins International. Partners include Superganix, Surge Running, Celsius, Arvada Tri, Planet Fitness Arvada, Renewal by Andersen, and Gu Energy Gels. Visit the organization's website for the most recent information.
