Groundhog Day Marathon

Embrace the chill and the unique challenge of the Groundhog Day Marathon and Half Marathon, returning to Grand Rapids, Michigan, on February 7, 2026. This distinctive winter running event, held within the expansive and scenic Millennium Park, offers participants the opportunity to "relive the day" on a certified course. True to its name, the marathon covers 12 loops, while half marathoners complete 6 loops, creating a memorable experience where camaraderie flourishes as runners repeatedly encounter one another.

The course itself features mostly paved trails, including sections of the Kent Trail and Fred Meijer Millennium Trail, with approximately a mile of crushed limestone mixed in. Each loop presents a modest 50 feet of elevation change, offering a gently rolling challenge. Runners should come prepared for typical race day conditions, which often include frigid temperatures ranging from 16F to 31F, with a 10% chance of precipitation and a high likelihood of snow or ice on the course, as it is not cleared. Frequent aid stations are a welcome sight on the looped course, providing ample opportunities for refueling and support.

Conceived from a desire to "embrace the cold and snow" rather than lament it, the Groundhog Day Marathon has cultivated a reputation as a fun and engaging winter race, offering a rare opportunity for a February marathon in the Midwest. Runners consistently praise the friendly atmosphere and unique format. Starting behind the pavilion in Millennium Park's Meadows, this event promises a rewarding and spirited running adventure for those ready to tackle Michigan's winter landscape.
