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.
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 2023 race includes a virtual option, which you can run anytime from November 12 to November 26.

I signed up for the half marathon over 6 months ago. I will not be able to run do to work. When I signed up I was off on Saturdays but I changed my job and now work on Saturday. Can I get a refund on the race?
Thank you
