Popeyes Backyard Ultra

Popeye's Backyard Ultra Greenland Open Space takes place on April 3, 2027, at the picturesque Greenland Open Space near Larkspur, Colorado. The race begins promptly at 7:00 AM and continues through a loop course of 4.167 miles until just one runner remains standing. Nestled in Douglas County's Palmer Divide, this expansive open space offers rolling grasslands, oak draws, ponderosa pines, and rocky mesas with the Front Range as a breathtaking backdrop.
Early April brings unpredictable weather to Greenland Open Space, transitioning from sunny days to possible snowfall within hours, adding an element of challenge for participants. The race follows strict Backyard Ultra rules: every hour on the hour, runners must start another lap together if they are still in contention. Completing each yard under one hour keeps you in the running; miss a bell or fail to finish within that timeframe and your race is over.
The course features dirt trails with crushed gravel sections, winding through diverse terrain from rolling hills to rocky mesas. Aid stations staffed by volunteers provide support between yards at the trailhead where runners can rest, refuel, and strategize with their crews. Headlamps are required for any yard that starts after sunset as Douglas County has granted permission for the race to run into the night.
Despite its challenging format, Popeye's Backyard Ultra is known for fostering a welcoming atmosphere among participants who cheer each other on through long hours of competition. This inaugural event aims to set a precedent for future races by adhering strictly to rules while ensuring all runners feel supported and encouraged throughout their journey.
The race welcomes up to 200 runners with an entry fee of $95, providing access to course amenities like port-a-lets and aid stations without the need for additional fees. Registration closes on March 31, 2027, at 11:59 PM MT.
Popeye's Backyard Ultra is a unique endurance challenge that celebrates perseverance in nature’s raw beauty.
