The Timberline Half Marathon is actually longer than the usual 13.1-mile distance for a half — it follows a 14.2-mile out-and-back loop course that starts and finishes just south of the lake, on Oregon Skyline Road. From there, runners follow the marked trail around Timothy Lake in a counter-clockwise direction, running past Hoodview and Pine Point around the southern edge of the lake, with views of Mount Hood off in the distance.

Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
