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!

Secret City Half Marathon and 5K      Date: November 21, 2020

The half marathon route starts at the scenic Melton Lake Park peninsula. Enjoy 13.1 miles of mostly flat terrain.  Considered a great PR course!  Course runs along the beautiful Melton Lake then down by an operational quarry for a change of scenery. Continue along a serene tree-lined private road then wind through Oak Ridge.  Finish your race along the water's edge right back to the peninsula.  Course is USATF certified with certification # TN15066MS.

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
