Course Overview
The Sky Pilots Ouray Backyard Ultra follows the classic format: complete a 4.167-mile loop in under an hour, then do it again. The race continues until only one runner remains, who must complete one final loop to claim victory. What makes this backyard unique is its straightforward course through the scenic Colorado town of Ouray at 7,700 feet elevation. The loop itself is deceptively easy—an out-and-back route with just 140 feet of elevation gain that winds through Fellin Park's asphalt track, smooth dirt roads, and the wide Uncompahgre River Walk. Runners follow the river downstream to a turnaround near falls, then retrace their steps back to the start. The path is broad enough for easy passing, and restrooms are strategically placed along the route. While the terrain won't challenge experienced trail runners, the altitude can become a factor as the hours accumulate and fatigue sets in. This race suits runners looking for their first backyard ultra experience or those wanting to test their endurance limits without technical terrain getting in the way. The format rewards steady pacing and mental resilience over speed, making it accessible to runners who can maintain a comfortable 14-minute mile pace but demanding for anyone hoping to outlast a determined field.
