Lace up for an unforgettable trail experience at the Earth Day 50k/15 Mile/5 Mile race, set to unfold on April 18, 2026, in the scenic Veteran Acres and Sterne's Woods of Crystal Lake, IL. Organized by the community-focused Ornery Mule Racing, this event is celebrated for its welcoming atmosphere and meticulous attention to detail, making it a "suburban hidden gem" for runners of all abilities. Choose your challenge from the 50K ultra, a demanding 15-mile run, or a spirited 5-mile option, all taking place on a beautiful 5.2-mile looped course.

The course itself is a runner's delight and challenge, winding through single-track trails, rolling hills that may require some walking, open prairies, and serene pine forests. Expect to be immersed in blossoming spring landscapes, navigating roots and natural terrain along the way. Runners consistently praise the race for its well-stocked aid station at the start/finish line, offering a delightful array of homemade goodies alongside typical ultra fare like cookies, soup, PB&J, and sports nutrition. As part of its commitment to environmental sustainability, the race strives to be "landfill-free," encouraging participants to bring their own water bottles.

Typical race day conditions in mid-April feature comfortable highs around 58F and lows near 38F, with a modest 16% chance of precipitation, offering pleasant running weather for an 8 AM start. Beyond the scenic and challenging terrain, the Earth Day race distinguishes itself with unique, often artist-designed or hand-painted finisher medals, a testament to Ornery Mule Racing's dedication to creating a memorable experience. Whether you're aiming for a personal record on the trails or seeking a supportive community race, the Earth Day 50k/15 Mile/5 Mile promises a rewarding adventure.
