Prepare for an extraordinary running experience at the Groundhog Run, returning to Kansas City, MO, on February 1, 2026. This unique event, celebrating its 44th annual running, offers participants the choice of a 5K or 10K, along with a "Tunnel-to-Tunnel" challenge that combines both distances. What truly sets the Groundhog Run apart is its unparalleled course: runners navigate a USATF Certified route entirely underground within Hunt Midwest's SubTropolis, the world's largest underground business complex.

Escape the typical February chill, where outside temperatures average highs of 41°F and lows of 22°F, as the SubTropolis maintains a consistent and comfortable 65-68°F climate, making it an ideal winter race without battling the elements. The course itself features paved, brightly lit roadways, offering a mostly flat profile with only minor elevation changes, turns of varying degrees, and a switchback to keep things engaging. While some runners note the scenery can be somewhat uniform within the underground facility, many appreciate the novelty and unique environment, highlighting the opportunity for fun photos. Good volunteer support and efficient logistics, including timely bus shuttles from parking to the start line, contribute to a smooth race day experience.

Beyond the distinctive setting, the Groundhog Run holds a strong reputation as one of Kansas City's favorite events, renowned for benefiting children with disabilities receiving services at Ability KC. Since its inception in 1982, the race has raised millions, directly supporting vital therapeutic and educational services. Participants will find packet pickup convenient, available on the days leading up to the event or on race day morning at Hunt Midwest SubTropolis. Runners should be aware that while the underground environment is climate-controlled, some have mentioned the air quality can feel stuffy with a large crowd. Whether you're seeking a personal best on a flat course or simply a truly one-of-a-kind winter running adventure for a great cause, the Groundhog Run delivers.
