The course uses an out-back format along the Catharine Valley Trail. Starting from Watkins Glen HS's athletic stadium (rear of the HS) it runs south, passing through the town of Montour Falls on its way to a turnaround point just shy of Millport. The surface is packed cinder w/ pavement through Montour. It's mostly flat for the opening/closing 3.5 miles w/ a gradual uphill from miles 3.5 to 5 (which you'll get more than paid back through its corresponding down on the return). It's a pretty fast course, good for both first-timers and those looking for a near-PR time.
