Yellowbrick Backyard Ultra - Peoria, IL

Yellowbrick Backyard Ultra is a backyard-style footrace held at Kinsey Park in Peoria, Illinois. The course is a 100% single track trail through a Wizard of Oz themed park with no road crossings or water crossings. The loop has small rolling hills with approximately 70 feet of elevation gain per mile.

The event uses a last-runner-standing format. Runners complete a repeating 4.16 mile loop that starts every hour on the hour. Competitors who do not return to the start line in time or who are not at the start line at the hour are removed from the race. There will be a five minute and one minute warning before each loop. No pacers are allowed on the course; crews may assist between loops. Except for restroom breaks, runners must remain on the course until they complete each loop. When a runner drops they must notify race staff before returning to their vehicle.

Packet pickup is available Friday June 12 from 4:00 to 7:00 PM and race morning from 6:00 to 7:45 AM at the start/finish area. All entrants receive a T-shirt, sticker and participant award. There is an award and prize for the overall winner and additional goodies for runners who reach 50k, 50 miles and 100 miles.

The aid station will offer a variety of snacks and warm foods as the event progresses and will provide water, Gatorade and soda. Dogs are allowed at the start/finish area on leash but may not pace runners. Camping in the park is not permitted; there are hotels within a 15 minute drive. Registration closes May 13.
