Set against the stunning backdrop of Auburn, California, this looped trail event invites runners of all paces to push their limits (or simply enjoy the journey) on a meticulously designed 0.75-mile course and paved bike path, featuring a beautiful pond, shaded paths, and much more for an unforgettable experience.

With exceptionally long cutoffs and no strict time pressures, whether you're walking, running, or crawling, there's space for everyone to shine and even earn one of the coveted Mile Madness Buckles. 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 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); in 2025, we were 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 receive MudGear/Mile Madness co-branded socks, a long-sleeve hooded tech shirt, and possibly more... We cannot guarantee sizes for registrations after 9/1/26, 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 the next year if you can't run due to 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, 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 just the thrill of the loop, we're here to support you through every step. We may have the best volunteers in the business. New 3-Hour Race: We have wanted to offer a 3-hour race as a shorter option than the 6-hour race. This is the perfect opportunity to experience looped-course racing, or for family and crew who may want to do fewer laps but still participate in the race. The 3-Hour race is priced lower and includes Co-Branded Mudgear/Mile Madness Socks and a shirt, food, and all amenities. The 3-Hour will not receive the larger SWAG item that the longer races keep, and the registration cost will be lower. 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 you
