Yellowbrick Backyard Ultra

Embark on an extraordinary challenge at the Yellowbrick Backyard Ultra, set to test your limits on June 13, 2026, in Peoria, IL. This premier "last runner standing" event unfolds at Kinsey Park, a uniquely themed Wizard of Oz locale that adds a touch of whimsy to the grueling endurance test. The course itself is a runner's delight and challenge: a beautiful 4.16-mile loop entirely on single-track trails, devoid of roads or water crossings. Runners will navigate hilly terrain, encountering roots and rocks, while enjoying the natural scenery populated by deer, birds, squirrels, and the occasional "Flying Monkeys."

The Yellowbrick Backyard Ultra is Central Illinois' only event of its kind, where mental fortitude proves as crucial as physical stamina. Each lap begins precisely on the hour, every hour, pushing participants to strategically manage their pace and recovery time. The atmosphere is vibrant and supportive, with many runners aiming for a new personal best, using it as a training ground, or simply enjoying time on the trails with fellow enthusiasts. Typical race day conditions in mid-June feature comfortable highs around 84°F and lows near 63°F, with a 17% chance of precipitation, creating a dynamic environment for this continuous challenge.

A well-appointed aid station at the start/finish area in Kinsey Park ensures runners are well-supported between loops. Expect a diverse selection of fuel, including chips, pretzels, cookies, candies, sandwiches, and fruit, with warm options like pizza rolls, soups, potatoes, quesadillas, and hot dogs becoming available as the race progresses. Hydration is covered with water, Gatorade, and soda. Runners and their crews are encouraged to set up personal aid stations—a chair, cooler, or even a 10'x10' pop-up tent—to maximize comfort and efficiency during those critical hourly breaks.
