The Groundhog Day Marathon is an annual winter running event held in Grand Rapids, Michigan, known for its unique "Groundhog Day" movie-themed loop course. The race takes place on a certified course, primarily on paved and crushed limestone trails within Millennium Park, which offers a beautiful, wintry backdrop. Runners have the choice of multiple distances, including a full marathon, half marathon, and a shorter "Moonlight 1/6 Marathon," with special "Half Hog" and "Whole Hog" challenges for those who complete a combination of races. This unique format of reliving the same course multiple times is a nod to the classic film and makes the event a popular choice for runners seeking a memorable winter challenge and a Boston Marathon qualifier.
