Secret City Half Marathon and 5K

In person on November 20th, Virtually November 13-27 Directions
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!

TORCH aims to serve the homeless, those who are in jeopardy of becoming homeless, and those who are not able to receive services elsewhere due to lack of documentation (i.e. No ID, no phone, no address –or other limiting factors). We work to help them obtain the basic necessities to receive services.

The half marathon route starts at the scenic Melton Lake Park peninsula.  Considered a great PR course!  Course runs along the beautiful Melton Lake then down by an operational quarry for a change of scenery.

The 5K race route starts and finishes at the Melton Lake Park peninsula.  The course follows the water's edge along Melton Lake to Elza Gate Park then double back down the walking trail to the peninsula.  A very scenic, easy,  and enjoyable 5K run. Cert #: TN15077MS
