Secret City Half Marathon
Race Day Weather
Cool start — fast day potential, warming through the race
A cool 44°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 59°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

Race Info
The Secret City Half Marathon and 5K takes place each November in Oak Ridge, Tennessee, a city built in secrecy during World War II for the Manhattan Project. Both courses start and finish at the Melton Lake Park peninsula. The half marathon runs along Melton Lake, past an operational quarry, and down a tree-lined private road before returning along the water to the finish. The 5K stays along the Melton Lake walking trail out to Elza Gate Park and back.
