About the Event

The Endless Day Backyard Ultra returns to Richfield, Utah on June 27th, challenging runners with a unique format that blurs the lines between endurance and ingenuity. This isn’t your typical ultra; it’s an event where every 90 minutes marks the start of a new lap around the same loop of flat dirt roads through farm fields near Nielson Family Park. Richfield stands ready to host participants from dawn until dusk, or even longer if you’re up for it.
As day turns into night and back again under Utah’s vast summer skies, runners will navigate an ever-repeating 6.55-mile course framed by the rolling hills of the Pahvant Range and Red Hills in the distance. The atmosphere is one of camaraderie and shared struggle; each lap completed brings a deeper connection to both the landscape and fellow competitors pushing their limits against time and terrain. It’s more than just running; it's about embracing what the day has to offer, whether that means enduring relentless heat or reveling in moments of cool twilight.
Since its inception, this event has grown into a cornerstone for endurance runners who seek not only personal achievement but also community support. Whether you’re aiming for one lap or pushing towards 15, every milestone earned comes with recognition and respect from those around you. The Endless Day Backyard Ultra raises funds to benefit local initiatives that enhance the quality of life in Richfield by fostering health and wellness within the community.
The course itself winds through flat dirt roads bordered by vast farm fields stretching out into open vistas beneath a perpetually blue sky. Starting at Nielson Family Park, participants begin their journey on city streets before transitioning onto rural paths where shade is scarce but views are plentiful. Each lap covers 6.55 miles and must be completed within 90 minutes; the route includes two aid stations—one mid-way along Sod Farm Road near Highway 89—offering full hydration, sustenance, and medical support should it be needed.
With temperatures soaring around Richfield in late June, prepare for a day of intense heat and relentless sun exposure. The average temperature hovers at about 21°C (70°F), but the real challenge lies in managing humidity levels below 35%, ensuring that sweat evaporates quickly while also demanding vigilant hydration strategies from all participants. Ice-filled coolers will line the route, providing relief during your journey around this endlessly compelling loop.

The start location is located conveniently within the park itself, where you can also pick up your packet and any last-minute gear needed for your endurance quest. The event welcomes runners of all ages but does require participants to be at least 18 years old due to liability concerns regarding extended exposure and physical exertion over such a long period.
