Held on the second weekend of August every year is a bike race called the Tour de Millersburg. The bike race has a race each day (time laps don't count). The Saturday race starts and ends at the corner of Church & Moore Streets and goes down to Union Street, then goes up Race Street, and across Bowman Street (maybe), then heads down Church Street and back to the starting line. There is a pit stop at the corner of Race and Herman Streets. The Sunday race heads through the countryside. It starts at the famous gazebo at the square where US 209 meets PA 147. It involves a back road called Shippen Dam Road. The route involves PA 25. For both races, there are motorcycles at both the beginning and end of the line of racers to signal the line of racers beginning and ending. During the race no car can proceed through any intersections until the line of racers completely passes by. For more information, visit the Tour de Millersburg website, at www.tourdemillersburg.com.
