Course Highlights: A compact 0.75-mile loop means continuous laps with easy access to aid stations, festive decorations, and upbeat music to keep your spirits high. Aim for that first ultra milestone or chase elite goals—many of our runners discover untapped potential here. The course will be professionally measured prior to the race.

Why Mile Madness?

Inclusivity for All: We had runners from under age 10 to runners and walkers in their 80's, with a balanced mix of 52.8% male and 47.2% female participants. In 2024, we welcomed 115 runners with a remarkable 72% buckle completion rate (applies to 48- and 72-hour runners); in 2025, we were 140 strong, and in 2026, 181. Beginners who've never run an ultramarathon often surprise themselves with distances they never imagined.

Top-Notch Support: Fully stocked aid stations featuring a rotating menu of hearty meals, electrolytes, all the typical aid station food, and endless encouragement from what might be the best trail-running volunteers. Other amenities include on-site massage therapists, family cheer zones, glow run, food trucks, and more...

Bling & Bragging Rights: Earn the coveted Silver 100-Mile Buckle (many trying an ultra for the first time) or challenge yourself for the stunning Gold 150-Mile Buckle or the 200-Mile Buckle. Plus, a 100% rollover policy up to 24 hours before race start means zero risk if life throws a curveball.

SWAG: Every registered runner will receive amazing SWAG. In 2026, every registered runner received MudGear/Mile Madness co-branded socks, a long-sleeve hooded tech shirt, and a waterproof picnic blanket... We cannot guarantee sizes for registrations after 8/1/27, but we will do our best to accommodate requests. 

Bib Raffle:  We will hold a bib raffle at regular intervals during the race. Registered runners will be entered into the raffle. It's a bonus: you might walk away with fantastic prizes, including shoes, handheld bottles, an antichafe stick, and more. Why should podium winners get all the bling?

Family & Community Focus: Bring your crew! Our expansive UltraLounge, which offers shaded comfort, music, free snacks and water, games, festive decorations, S’mores, and a DIY sign-making station to fuel the fun. Come solo or with friends—you'll leave with new bonds, shared stories, and memories that last a lifetime. Runners rave: "The highlight of my year!" (Summer W.) and "My favorite race ever!" (Shawnee).

Worry-Free Guarantee: We will roll over your race entry to next year if you can't run because of injury, training challenges, or any other reason. We want you to enjoy the race you pay for, and we understand that life happens.

Extra Perks: Plenty of clean restrooms with showers, spots to "rest" in tents when you need a break (we can't call it camping), and a commitment to giving back through the Run Free Foundation, whose mission is to empower at-risk youth and runners facing financial barriers by providing access to quality running gear and race registration scholarships, enabling them to pursue their athletic dreams and enhance their well-being. 

Mile Madness isn't just about the miles—it's about the madness of joy, grit, and connection that turns strangers into trail family. Whether you're chasing a PR, your first buckle, or the thrill of the loop, we're here to support you every step of the way. We may have the best volunteers in the business.

Ultra Lounge: The family cheer zone is getting a more fitting name. We are borrowing the Ultra Lounge name and will have our 13x26 wedding tent with fun activities that will keep your crew going so they can keep cheering you on.  We will have food and water, a poster-making station, a glow party, cornhole, and more... Don't forget the running movies, fire pit with s'mores, and games for your crew and family while you crush miles.

Referral Rewards: We want to reward you for referring other runners to Mile Madness.  When you register, you will get a referral code to share.  Have your family, friends, or social circle use that code, and you will receive a refund for every referral.

Earn $10 for any 6-Hour or 12-Hour referral.  Earn $20 for each referral to the 24-Hour or longer races.  The refund will happen automatically, and the referral code must be used by the person registering.
