The Secret City Half Marathon & 5K Races

      Oak Ridge, a bustling city created virtually overnight in the foothills of the Great Smoky Mountains, was shrouded in secrecy for most of the 20th century; only appearing on maps in the mid-1960's.  Today, Oak Ridge is on the map as a thriving city rich in cultural and recreational opportunities not to mention the cutting edge science and technology research for which the city is internationally known! 

Come to Oak Ridge and experience for yourself.....a one of a kind Tennessee half marathon and fun 5K race event!
