Estes Parks Backyard Ultra

The Estes Parks Backyard Ultra returns to the scenic town of Estes Park in Colorado on June 27th, 2026, promising a unique challenge for runners willing to test their endurance and perseverance against nature's backdrop. This year marks its debut with an afternoon start at 4pm, allowing participants to escape the midday heat while experiencing the serene evening light over Lake Estes.
Set along the picturesque shores of Lake Estes, this ultra-distance event unfolds on a well-maintained paved bike trail that winds through the heart of the town. The route offers runners stunning views of the surrounding Rocky Mountains and the shimmering lake waters as they traverse each challenging mile. Participants will start their journey at 380 Community Dr., heading clockwise for the first stretch, before switching directions every twelve hours to keep things dynamic.
Since its inception in Estes Park, this Backyard Ultra has quickly become a cornerstone event that not only pushes physical boundaries but also supports local causes deeply ingrained within the community. This year's race will benefit Childcare and Family Services of Estes Park, an organization dedicated to providing essential support for families throughout the region. Each participant who signs up contributes directly towards these efforts by paying a $120 fee.

The course itself is meticulously designed with one lap measuring 4.252 miles, including a significant elevation gain of 150 feet per yard and an overall climb of 7,522 feet throughout the race duration. The terrain consists primarily of firm ground that remains slightly soft in places, offering both stability and challenge to runners as they navigate around Lake Estes.
Starting from 380 Community Dr., participants will encounter a well-lit environment conducive for night running once darkness falls. Aid stations are strategically placed along the route to provide necessary hydration and nutrition throughout the race's duration. As the event progresses, runners can expect varying directional changes every twelve hours, adding an element of surprise and strategic planning.
Given Estes Park’s climate in June, participants should prepare for average temperatures around 13.4°C with a high chance of slight rainfall due to the region’s typical precipitation levels at this time of year. Humidity tends to hover around 62.6%, creating a damp but not overly oppressive atmosphere as runners tackle each lap under firm and slightly soft trail conditions.
