Secret City Half Marathon and 5K
Saturday, November 14, 2026Oak Ridge, TN5K – Half Marathon
The Secret City Half Marathon and 5K offers runners a scenic tour of Oak Ridge, Tennessee, starting and finishing at the picturesque Melton Lake Park peninsula. The half marathon is widely considered a fast, PR-friendly course that winds along the serene Melton Lake waterfront. Runners will experience a unique change of scenery as they pass by an operational quarry and navigate a quiet, tree-lined private road. The 5K route provides a shorter, equally beautiful experience, following the water's edge to Elza Gate Park before returning to the peninsula. Both courses are USATF certified, ensuring a high-quality racing experience for participants of all levels. Whether you are chasing a personal best or enjoying a peaceful run, this event highlights the natural beauty and historic character of the Oak Ridge area.
