Filled with rolling hills along the rural countryside of Maryland’s upper Montgomery County, just across the Potomac River from Virginia, the Riley’s Rumble Half Marathon takes runners on an out-and-back course that starts and finishes at the Riley’s South Germantown Recreation Park.
This popular warm-up event for the regional marathon events that take place later in the fall usually attracts 500 runners or more each year, so prospective entrants are encouraged to register well in advance of the race before it fills up.
From the starting line on Central Park Circle inside the park, runners follow a course that takes them northward and then westward all the way to the first turnaround point on Barnesville Road, and then back down White Ground Road to the intersection with Old Buckbridge Lane, where they turn and make their way up to the second turnaround point roughly a mile up the road.
From there, runners follow the course they’ve already run for the first half all the way back to the finish line at South Germantown Park.
