Race Overview

We’ve all heard of Punxsutawney Phil, the little furry guy in Pennsylvania who comes out, sees his shadow, and declares six more weeks of winter. Then there’s Augustus T. Groundhog, better known as Grand Rapids Gus. He’s Phil’s much more interesting cousin. Unlike Phil, who it seems can only see shadows, Gus has much better eyesight and can look at a calendar on February 2 and know that spring doesn’t start for six weeks. Gus suggested that instead of lamenting over six more weeks of winter, we should EMBRACE the cold and snow and do something fun. And so, the Groundhog Day Marathon was born.

The modified course for 2024 was pretty popular. We've certified the new course, so we’ll be starting behind the pavilion this year again. Looking forward to seeing you in 2027!

Weather Warning

This is a middle of the freakin' winter thing. Weather could suck. (Usually does.) You do know we’re in Michigan, right? So register at your own risk. There are no refunds, deferrals until Friday of race weekend, no transfers. If there’s a snowstorm of Biblical proportions, we’ll have a snow date the next Saturday. If it’s still not possible to hold the event, we’ll give people registered for this year a 50% credit on next year’s event.
