Machete Trail Madness, a movement established in 2014, prides itself on being one of the toughest ultramarathons in the USA, offering generous cutoff times to support every runner's journey to the finish line. The multi-lap format cultivates a unique and interactive atmosphere, allowing runners to engage with each other and offering ample opportunities for family and crew to provide support at the start/finish area, which doubles as a transition zone. Full aid stations are strategically placed at mile 6 for 50K runners, and at miles 8 and 12.8 for those tackling the 100K, ensuring runners can refuel and rehydrate with ease on each lap.

Beyond the physical challenge, this race is celebrated for its strong community spirit and dedicated volunteers who provide unwavering encouragement throughout the night. Runners consistently praise the event for its challenging yet rewarding experience, making it a favorite ultra for many. Adding to the exceptional value, participants can enjoy complimentary camping at Group Camp #3, located next to Hunters Parking Lot at Lake Perris, which serves as the central hub for the race. Free Cold FitAid at the finish line and professional race photos further enhance the Machete Madness experience, making it far more than just a race.
