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--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 closest to Groundhog Day February. In 2024, it's February 2-3.

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

Our Events
Like the movie, you’ll feel like you’re repeating the same day over and over. A beautiful, snowy (we hope), approximately 4.4 mile course. Splits every 1/6th 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 three times around.
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.  6:30 p.m. Friday. 300 Runner limit.

Ever see the movie?  The course will give you the opportunity to relive the same day several times.  A total of 6 loops of approximately 4.4 miles on a CERTIFIED course (Yes!  You can qualify for Boston!) will have you feeling just a little case of deja vu.  Two aid stations 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 and a pretty nice bag of Ka'Chava protein powder.


Training Partner - And our Official Training Program for Groundhog

RunGR is our largest local running club and has multiple coaches, who provide training programs for all of our races. With a club of more than 300 runners, the club provides a great opportunity to not only get a coaching plan, but also do your training with a large group of local athletes. RunGR will be offering a training plan, specific to Groundhog distances, as well as a prorated membership, known as their FAST program, so you can try out the club for 20 weeks.

This is a middle of the freakin' winter thing.  Weather could suck.  You do know we're in Michigan, right?  So register at your own risk.  There are no refunds, no deferrals, 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.

Race Weekend Info

AID STATIONS Aid stations are at about .2 miles and 2.4 miles on the loop. A little extra at the Start/Finish just in case. Water and Gatorade.  We aren’t supplying any energy gel, so bring your supply or pick some up from Striders. And DON’T THROW STUFF ON THE TRAIL! (gel packets, cups, etc.) it’s winter and we’ll never find them to pick up in the snow.

AWARDS Overall winners (Male & Female) in the full and half get an amazing piece of Groundhog art by local chainsaw artist Jack Eppinga. Other than that, coffee mugs for age group awards (3 deep) and of course, finisher medals for all three events. FIVE YEAR AGE GROUPS. If you have any chance whatsoever of winning the overall race, start at the front so we don't have any confusion on gun vs. chip time. (We're basing all awards on CHIP TIME.) 

OVERALL AWARDS i.e. the really cool Groundhog Trophies, chip time due to the crowded starting area.  If you have any chance whatsoever of winning the overall race, start at the front so we don't have any confusion on gun vs. chip time. (We're basing all awards on CHIP TIME.)  All Age Group awards will be based on CHIP TIME, since the narrow starting area is hard to get everyone who's fast right up by the starting line.

COOLEST GROUNDHOG CONTEST We’ll be picking the best dressed Groundhog and reward that person with a little bit of extra swag.

COURSE  Yes, we already talked about that. NO, the course won’t be free of snow unless Mother Nature (or some other mother…) deems it so. If it’s really bad we’ll actually groom it so that it’s not as bad as it was in 2014 just to keep people from jumping all over Marathon Don’s back. In case of REALLY SEVERE conditions, we have a certified alternate route that's 12 loops instead of 6, but our timing guys really hope we don't have to use it.

EARLY START: If you're going to be on the course after 3pm, start at 7 for the early start OR start at 6 and run your own stopwatch. Report to the Classic Race table in the tent before you start and when you finish--we'll still include you in the official results. Timing mats will be on for the 7am start.

HEADLAMPS The Moonlight event on Friday night, (the 1/6 marathon) HEADLAMPS ARE REQUIRED. Bring yours from home. We're not sure that anyone will be around to sell you one on site. (Dude! In 2017 we actually saw the moon!!)

HOODIES To guarantee a hoodie size will be available on race day, please get registered ASAP. Everyone will get the swag, but we don’t wish to have tons of them left over. If you sign up on race day, you’ll have to wait until after the full and half start to make sure we have the right size for you. If we run out, we’ll get you one afterwards. (Oh–there are no XS hoodies)

On Friday, at the race site (1400 Maynard) from 4:30PM – 7:30PM and then beginning at 6:30 a.m. on Saturday. 

PARKING The race venue may be limited with parking, but we have LOTS more than in the early years. Carpooling is recommended if you can.

START TIMES 6:30PM Friday for the 1/6 marathon.  8:00AM Saturday for the full and half marathon. Early start on Saturday at 7:00AM

SWAG Hoodie for each runner in the 1/6, Full, and Half. For those running the 1/6 on Friday, then the full or half on Saturday, you’ll get a hoodie and an embroidered stocking cap. Finisher medals for all 1/6 marathon, marathon and half marathon finishers.

SWAG SHOP We'll have old sweatshirts, and various merchandise on sale CASH ONLY. Bring a few bucks.

SWITCHING RACES It is allowable to switch from the full to the half (or vice versa if you’re feeling really frisky) but you need to make sure the timers from Classic Race Management know that BEFORE the race. (Cash bribes might help.) Switching mid-race isn’t cool, but if you happen to do that, you better go up to Jeff from Classic and talk REAL NICE to him, and maybe he’ll include you in the results anyway. (We have a few people get on the course and decide to switch to the half marathon. We can work with that!)

WAVE START Yeah, we tried to do a wave start, but you people seemed content to start at your leisure so to heck with that idea. Competitive runners, be at the starting line on time, and we’ll send you off. If you have any chance whatsoever of winning the overall race, start at the front so we don't have any confusion on gun vs. chip time. (We're basing all awards on CHIP TIME.)  After that, the “less focused” runners can cross the starting line–heck, we have chip timing anyway, so you’ll get an accurate time regardless. NOTE: PLEASE START IN THE FIRST COUPLE OF MINUTES. DON’T SIT IN THE TENT HANGING OUT! IT’S NOT GOING TO GET ANY WARMER IN THE NEXT 5 MINUTES.

Frequently Asked Questions

Where is this event?
It's in the United States. Grand Rapids, Michigan. It's not the event in Telford, England. That one is HERE But our friends from across the pond are welcome to join us. Just think--run two Groundhog Marathons in the same year. Who does that???

What is the weather going to be like?
There are professionals who do weather predictions. We’re not them. (And Punxsutawney Phil, out in Pennsylvania supposedly does weather predictions too. Grand Rapids Gus, however, doesn’t give a s…) THERE COULD BE A LOT OF SNOW ON THE COURSE.

I thought you were going to keep it on Groundhog Day. What’s the deal?
We took a poll. People thought it would be better to keep it on the weekend. So we’re keeping it on the weekend. Don’t say we never listened to you. Christmas has to stay on the 25th, but we’re trying to make this more convenient for our runners, so we’re moving it slightly off the 2nd some years. (Come to think of it, I think the poll was more among staff members who couldn't stay awake for the Super Bowl when we held it on Sunday a couple times.)

Is this a Boston Qualifier?
It’s winter. It’s paved trails but there may be two feet of snow on them. But the course is certified. So, yes, if you can finish in a BQ time it’s a Boston Qualifier.

Will there be finishers’ medals and shirts?
This marathon is managed by professionals. We’ll have Gatorade and water too.

Will there mile markers and aid stations on the course?
There are 4 mile markers on the course. It’s 4.4 miles long, so putting more than that would just be silly. There are two aid stations.

Can we wear costumes?
We’re not going to discourage it. You can run naked for all we care.

Will there be a live groundhog?
Maybe. Maybe some dead ones too. Then there’s the groundhog puppet that Don uses to flirt with girls.

Is this a walker friendly race?
Walker friendly, yes.  Please walk fast so we don't all freeze while waiting for you. If you're going to be on the course after 3pm, start at 6 or 7 and run your own stopwatch. Report to the Classic Race table in the tent before you start and when you finish--we'll still include you in the official results.)

Are past results available?
Yes. 2019  2018  2017  2016   2015

Where’s the course map?
There's a link below for that. THERE COULD BE A LOT OF SNOW ON THE COURSE.

Where will the parking be?
There’s a bunch of parking on site. Carpooling is advised just to keep the congestion down. We’re at The Secchia Meadows. If we run out of parking there, we'll open the parking lot on the other side of Maynard.

If I don't show up for the race, can I still get my hoodie
Maybe. But you'll have to pick it up. We try not to have any leftover when we're done, so don't plan on it. Also, they cost about $7.50 to mail, so we're not really crazy about doing that. 

Is it OK if I throw trash on the trail?
NO! It's winter. It's really hard to find stuff in the snow. That's why we have cookies and peanut butter filled pretzels instead of gel packs at the aid station. Even if you bring your mom along to pick up after you, it's still NOT OK!
