WHY MILE MADNESS?
INCLUSIVITY FOR ALL: We had runners from ages 10 to 82, 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); 2025 was 140 strong, and we're projecting 200-250 for 2026. Beginners who've never run an ultramarathon often surprise themselves with distances they never imagined.
TOP-NOTCH SUPPORT: Fully stocked aid station featuring a rotating menu of hearty meals, electrolytes, all the typical aid station food, and endless encouragement from what might be the best volunteers in trail running. 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 (35 awarded in 2024, many to first timers!) or challenge yourself for the stunning Gold 150-Mile Buckle or the brand new 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 get a race shirt or jacket. Our current plan is to provide gender-specific, packable, puffy jackets. We cannot guarantee sizes for registrations after 9/1/26, but we will do our best to accommodate requests. All runners will also get additional SWAG that will be announced closer to race weekend.
FAMILY & COMMUNITY FOCUS: Bring your crew! Our expansive 20x30 Family Cheer Zone offers shaded comfort, music, free snacks and water, games, festive decorations, Smores, and a DIY sign-making station to fuel the fun. Come solo or with friendsyou'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).
EXTRA PERKS: On-site ultra-camping for immersive weekend vibes, plenty of clean, portable restrooms, 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 milesit'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 just the thrill of the loop, we're here to support you through every step. Secure your spot now and join the fun!
RELAY OPTION: We have a 72-Hour Relay and 48-Hour Relay
* Each relay team can have 4-10 runners. Each runner will register and pay a separate registration fee (which covers food, SWAG, and more) and select their relay team. Each team will share a single team bib with one runner at a time on the course. Other team members can use a Pacer bib to support their team member running with the team bib.
* Podium awards will go to the top three teams.
* Relay runners are not eligible to earn a 100-mile buckle (relay laps should be shared somewhat evenly between team members, so achieving 100 miles per runner is unlikely).
