The Little River Rush Half Marathon is a point-to-point half marathon in East Tennessee. It starts at the Smoky Mountain Heritage Center in Townsend and finishes at Heritage High School. Participants park at the high school and take a bus to the start line, running in one direction. The course descends over 600 feet, with a net downhill of more than 200 feet, earning its reputation as one of East Tennessee's fastest half marathons.
The route traces the Little River from Townsend along quiet back roads, offering mountain views and minimal traffic. It suits runners who prefer a consistent downhill gradient, though the setting remains rural and open for a significant portion. Finishers are awarded a custom medal, and race entries benefit the cross country and track and field programs at Heritage High School.
