From the Organizer

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! 

EARLY START--If you're planning to be running more than about 6 hours, please start at the 7:00 am early start. The normal start is at 8:00 am

The Basics
It’s a winter running event, outside Grand Rapids Michigan.  YES! THERE WILL PROBABLY BE LOTS OF SNOW ON THE COURSE.

The Friday and Saturday beginning of February. In 2027, it's February 5-6.

It’s more fun than you should have with your clothes on. (And we DEFINITELY suggest you keep your clothes on!)

Our Events

Friday -  Moonlight 1/6 Marathon on Groundhog Eve: WORLD CHAMPIONSHIP 1/6 MARATHON! Hey, we’re going to be set up anyway, no sense in just long-distance people having all the fun. Two loops of the course. 6:30 p.m. Friday. 300 Runner limit.


Saturday - Marathon: Like the movie, you’ll feel like you’re repeating the same day over and over. A beautiful, snowy (we hope), approximately 2.2 mile course. Splits every 1/12th of a marathon. 8:00 a.m. Saturday.  500 Runner limit combined for full and half marathons

Saturday - Half Marathon: For those of you who couldn’t stay awake through the whole movie. Only six times around.



Course
Ever see the movie?  The course will give you the opportunity to relive the same day several times.  A total of 12 loops of approximately 2.18 miles on a CERTIFIED course (Yes!  You can qualify for Boston!) will have you feeling just a little case of deja vu.  Aid stations at 1 mile plus the finish line area.  Don’t plan on the course being free of snow.  It’s paved, which means no underlying rocks and roots, but that’s about all we’re promising.

Swag - Every participant will get an awesome hoodie, finisher medal. Whole and Half-Hog get a stocking cap as well.

From Endurance Grid

About This Sport

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.

Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.

The half marathon rewards people who show up for the boring training miles.

How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
