Owls Roost Rumble

The Owls Roost Rumble returns to Bur-Mil Park in Greensboro, North Carolina. This popular trail race features a half marathon and a 4 mile run, with the option to ruck or hike the course. Set along the Greensboro watershed trails, the event highlights some of the most scenic and iconic singletrack in the state.

Perfect for beginner trail runners discovering the sport and seasoned trail runners looking for a challenging adventure, the Owls Roost Rumble offers a course with rolling terrain, lakeside views, and sections of varying difficulty. All participants receive a lightweight race shirt and a custom finisher medal, which is part of the Trivium Trail Mega Medal Series.

 
Why People Run the Owls Roost Rumble

• Scenic Greensboro watershed trails, including a full loop around Lake Brandt
• Options for all levels: half marathon or 4 mile run
• Run, ruck, or hike 
• Beginner-friendly course that also rewards experienced runners
• Well-marked trails with rolling terrain and varying difficulty
• Custom finisher medal that connects as part of the Trivium Trail Mega Medal Series
• Comfortable tech race shirt with unisex and women’s fit options
• Well-stocked aid stations with hydration and nutrition support
• A supportive community atmosphere that makes every finisher feel celebrated

The Owls Roost Rumble is more than a trail race. It is an experience that blends nature, endurance, and community. Whether you are racing for a personal best, challenging yourself with a ruck, or simply enjoying a spring morning on the trails, this race is one of the most rewarding trail events in North Carolina.

Our 4 mile course has been updated in the past two years to make this an even better beginner friendly race.  Athletes doing the 4 mile will start out by doing the first part of Big Loop.  This section of trail is very wide, and while there are roots on this section, Big Loop is wide enough that all roots are easily avoidable.  Runners will them get onto the A and Y Greenway and make their way to Little Loop.  Little Loop, much like its big brother, is a wide trail, but even less rooty.  This trail looks intimidating when you first enter it, as it starts with a slight climb, but it is one of the more tame trails in the area! Once done with Little Loop, athletes will make their way back to Big Loop to the finish!  This course can be raced, or walked and offers a variety of terrains.  We love this course because it is a great race for first timers and speed demons alike!

While we love the classic Owls Roost course, the reroute we are using due to greenway construction, is nothing if not beautiful and fun.  Athletes will get the same hard nosed experience on Owls Roost Trail, mixed with a bit more gentleness from trails like Nat Greene and Palmetto.  We will still have the classic Big Loop Trail to start and finish the race as well.  All in all this is going to be a great course and a great year!  Make sure to check out the course maps below for elevation, and course maps.
