Lace up your shoes for the Childish Nonsense race, a whimsical trail and ultra running event set to unfold on April 25, 2026, in the scenic Deer Grove Forest Preserve West in Palatine, IL. Organized by Cussing Runner, this event is celebrated for injecting fun and passion into the running scene, fostering a supportive community where every pace is welcome. Participants can choose their challenge from distances of 10K, 25K, 50K, and a demanding 50 Mile option.

The course is designed as a loop, guiding runners through the rolling trails of Deer Grove Forest Preserve. Expect mostly wide dirt paths with soft crushed gravel underfoot, offering a non-overly technical experience while still presenting some natural elements like rocks, roots, and ruts. The 50-mile distance, for instance, includes significant elevation gain, rated as hilly. Each loop measures approximately 5.5 miles, providing regular access to the sole aid station conveniently located at the start/finish area. Crews are welcome to set up at this central hub to support their runners, and 50-mile participants can bring in a pacer after completing four loops. Typical race day conditions in late April see comfortable highs around 61°F and lows around 42°F, with a relatively low 14% chance of precipitation.

What truly sets Childish Nonsense apart are the "shenanigans occurring throughout the day," designed to awaken your inner child and add a unique, playful spirit to your race experience. The event, known for its inclusive ethos, also actively promotes diversity by offering free entries to BIPOC and LGBTQ+ athletes. With an 8:00 PM cutoff time for all distances, runners have ample opportunity to embrace the challenge and the fun. This race promises not just a physical test, but a memorable journey filled with camaraderie and a touch of magic on the trails.
