Event overview

Prairie Chaos Backyard Ultra is an official Backyard Ultra held in Little Mountain Park, Winnipeg, MB on Saturday, August 15, 2026. The event uses a single trail loop of 6.7056 kilometers (4.167 miles) that passes through open prairie and shaded forest with roots, rocks, and rolling terrain.

The event provides a bib, race socks, a race Buff, and a "Did Not Finish" medal to participants, with a distinctive prize for the sole winner.

Race format, facilities and logistics

Each participant is allocated a personal station near the start/finish corral for crew and equipment. An aid station supplies water, an electrolyte drink, sweet and salty snacks, and some warm food overnight; participants are advised to be self-sufficient because supplies will be limited. Parking near the start/finish includes a main lot of about 40 spots, additional parking off Klimpke Road, and roadside parking on Farmer Road. There is an indoor lodge near the course with four lavatories, sinks, and a small sheltered area with a water fountain; the lodge will be available during specified hours. Portable toilets will also be staged close to the start/finish area. Race rules prohibit artificial aids, personal aid during a loop, and non-competitors on course; competitors must be inside the starting corral at the bell and complete each loop in less than an hour.
