Groundhog Day Marathon

Friday, February 5, 2027Walker, MI4.37 Miles – 50K

Embrace the winter chill at the Groundhog Day Marathon, a unique event inspired by the classic film where you'll experience a sense of deja vu on a repetitive, snowy course. Held in Grand Rapids, Michigan, this race features a certified loop course that allows runners to qualify for the Boston Marathon while navigating potential snow and cold. Participants can choose from the Moonlight 1/6 Marathon on Friday or the full and half marathon distances on Saturday. The event is designed to be a fun, lighthearted challenge that encourages runners to celebrate the season rather than hide from it. With a limited field size and a festive atmosphere, it is a quintessential Michigan winter running experience.
