Cool start — fast day potential, big temp swing

A cool 50°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 69°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

It returns on the Third Creek Greenway through Tyson Park and finishes in World's Fair Park in front of the World's Fair Exhibition Hall, after passing the Knoxville Museum of Art. The half shares its course with the marathon until the final turn toward World's Fair Park.
