Overview

East Tennessee’s Secret City Half Marathon takes runners along a fast and largely level course. The route follows the beautiful Clinch River with runners passing a quarry for a change of scenery. The course continues down a serene tree-lined road and through the heart of Oak Ridge. The route picks up the Clinch River again for impressive views all the way to the finish.

Course Description

Oak Ridge was a city created in secrecy literally ‘overnight’ in the 1940’s and played a vital role in helping to end WWII with the creation of atomic weapons. Nicknamed the ‘Secret City’ for its role in the war effort; Oak Ridge was not even on a map until the 1960’s.
Today, Oak Ridge is a vibrant city with scenic greenways, challenging hiking and biking trails, and beautiful waterways.
The 2024 race includes a virtual option, which you can run anytime from November 16 to November 30.
