Carri Compton | Race Director

This series is crafted to take all the stress away from race day. You get the same outstanding race expreince you would come to expect from a Mammoth event, just on your time. The six different trail systems we cover all have unique features about them and I love that. We experience big hills, fast courses, technical single track, gravel roads, amazing views, smooth wide trails and everything in between. Each race has its own personality that fits in perfectly with the others. 

The people are what makes this series so fun. Yes, we have the band, the food, the awesome trails, etc... but its the positivity, laughter, hard work and crazy stories that make the series what it is. If you don't know anyone yet, don't worry - you soon will. 

I can't wait to serve you on race day and help you with anything you might need. It's an absolute honor to direct these races and call you all friends. See you at the trailhead!

Start anytime Saturday 7:00am - 11:00am or Start anytime Sunday 7:00am - 10:0 Lets face it... race morning is stressfull! Getting to the start line in time for you to comfortably start without feelign rushed is one of the not so fun parts of racing. Lines at packet pickup, lines to go to the bathroom, lines to get your shirts - it all adds up and often gets our heart rate going before we even start running! Well, we're changing things up a bit.

Our signature stress free start gives you. the freedom to start whenever you want. You'll have a four hour window to start your race. As long as you cross that start line between 7:00am - 11:00am on Saturday - or, 7:00am - 10:00am on Sunday, you're good to go. No worries if you sleep in a bit or your friend is running a bit behind. Maybe you had to make 3 trips to the bathroom before hand LOL, we've beeeen there, we get it.

So, rather than stressing and feeling like you NEED to get to the race ASAP, get your stuff and get going. Enjoy your morning, walk a little slower and just enjoy the day and the oppotuniuty to race. Cruise through the Golden Kettle Village, have a beer while you listen to some live music.

Welcome to the most laid back starting experience you'll ever have.


We'll be getting back to having vendors, music and food / drinks as soon as we're alowed to. We're just as ready as you are!


In 2016, I found myself burnt of of pounding the pavement and hammering out mile after mile on the sidewalks. I was losing inspiration to run and needed a change. I had watched one of my brothers run the Pikes Peak Marathon the year before and was sort of intrigued at the idea of running up a mountain, just to turn around and run back down.. It sounded gnarly, and I was in. So, in 2016, I found a few local trails near Hartford, WI and started training on them. My 7:00min pace on the roads quickly fell to a 9:00 pace on the trails - woof this trail running thing was tough! A few months later i found myself at the base of Pikes Peak in Colorado, my first trail race ever. The race went fine, my body was destroyed from the elevation at 16,000ft & the pounding of a half marathon straight down the mountain. My body ached, my mind was exhausted, my knees bloody and as a laid in the grass in downtown Manitou Spring, i fell in love with trail running. Since that race, I've run less than a handful of road races and have dove head first into trail and ultra running. When i got home from Colorado, I needed to find more trails. So I began to hunt them down. One by one I started ticking off the trail systems both near and far. I loved every one more than the last. I took particular interest in the Southern Kettle because it was within 30min of my house and it seemed like I could connect trails easily and run for hours without ever running the same trail twice. In 2017, the idea was born of a trail running series. With my years of experience hosting road events all over the country, and my newfound love of trail running - I was excited and careful to put together a trail series that was special. It couldn’t be like the road events I had produced, it needed to be different and somehow stand out from the crowd. Finally, in 2020 I gathered the courage to put this thing in motion and got to work. We built the courses, built the look, pulled together the team and had our master plan in place. The product of many, many meetings, late nights, long runs and 17 years of producing events is what you see here. We're damn proud of this series and we want everyone to come experience the peace and beauty these trails offer. It's so much more than running a race - it's resetting your mind, moving your body, being quite and at times pushing your body harder than you think it can go. These trails hold a special place in the heart of so many people. I invite you out to the trailhead to see why we call these trail home and why they've changed so many lives and will continue to do so for many years to come. See you at the trailhead, Craig Braun (owner of Mammoth)


Just like last year, we can only have a limited # of runners. Because of this, we will not be. using shuttles at this years McMiller event. Parking is available at the trailhead.


Choose from any of our three courses. Short, Middle or Long distances are available. • Short Course The short course follows the red square markers on the trails. This loop will have one aid station available stocked with water (cup-less), tailwind and various sweet and salty snacks. 3.1 miles McMiller Trail System - Map • Middle Course The middle course follows the green circle markers on the trails. This loop will have one aid station available stocked with water (cup-less), tailwind and various sweet and salty snacks. 6.8 miles McMiller Trail System - Map • Long Course The long course follows the blue diamond markers on the trails. This loop will have three aid stations available stocked with water (cup-less), tailwind and various sweet and salty snacks. 11.8 miles McMiller Trail System - Map


Start anytime Saturday from 7:00am - 11:00am or Sunday from 7:00am - 10:00am We're still having to operate under strict restrictions. However, we will continue to. add things back as soon as they are allowed. Each race will be updated the monday before the event.


1. No Cups / No Single Use Plastic - You'll find a lot of useful things at our aid stations! Cups, however, are not one of them. Please make sure you have a handheld or pack to fill with water at the aid stations. We do not hand out water bottles at the finish line of our events. To reduce our use of plastic, we have a water fill up area that you can utilize to grab a drink and rehydrate after your race. 2. One Bib, All Series Long - That's right! Your race bib from race #1 is your race bib for the rest of the series! Not only does this reduce our footprint, but it also means you. can completely skip packet pickup at al the other races after you've raced the first one! After 16+ years of putting on events, and working to lower our. impact - it's silly to m that we print hundreds of race bibs to be used once and than thrown away. Why toss a perfectly good bib! Use that thing over and over again. If you forget yours or lose it, no sweat - we'll have extras at each race. 3. 80lbs a year! - The average American throws away 80lbs of clothing a year. If you're like me, you have SO many race shirts in your closet. We do not include a free race shirt with your registration, but rather give you the choice to see the shirt during registration and decide if you want it as an add on. We think our shirts are pretty awesome, but that doesn’t mean everyone needs one :). We also have really nice merchandise for sale at each race if the race shirt just isn’t your cup of tea. 4. Garbage Bins Everywhere - Get your trash in the bins! We've made the extra effort to have both garbage and recycling available inside the village. If one of our crew spots you tossing garbage on the ground we will immediately DQ you from the event. We take great pride in keeping these beautiful areas just how we found them. If you're not on board for that, you're on the wrong ship.


The Golden Kettle Trail Series is excited to announce two partners for our 2021 series. First, we will be working directly with the Department of Natural Recourses to help maintain and improve the trails and amenities in the Northern and Southern Kettle Moraine Units. Second, w're beyond excited to be partnering with Bigger Than The Trail, a 501c3 non profit that uses trail running as a platform to advocate for mental health, with the mission of enriching the lives of individuals struggling with mental health. Every time you race a Golden Kettle Trail Series event, feel good knowing you're a part of something bigger than yourself! Awesome!
