📅 2026 Date

Friday 6 February & Saturday 7 February 2026.

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 2026!

🏃‍♂️ Event 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.

⏰ Early Start

Early Start: If you're planning to be running more than about 6 hours, please start at the 7:00 am early start.
Normal 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 2026, it's February 6-7. It’s more fun than you should have with your clothes on. (And we DEFINITELY suggest you keep your clothes on!)

🏅 Our Events

Marathon: 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.
Half Marathon: For those of you who couldn’t stay awake through the whole movie. Only six times around.
Moonlight 1/6 Marathon on Groundhog Eve: WORLD CHAMPIONSHIP 1/6 MARATHON! Two loops of the course. 6:30 p.m. Friday. 300 Runner limit.

📏 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.

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.

You can transfer from one event to another--look yourself up and bring up your record. You’ll have to pay the difference between the events. No refunds.
