Event organizers are expecting over four-thousand runners in Saturday night's 25th annual Crazy 8s road race in Kingsport.
The Kingsport road race held the world record in the 8K for 18 years, but it was broken by one second last month during a race in Boston.
Lynchburg's Sam Chelanga finished third in last year's race. Friday he talked to News 5 WCYB about the possibility of a new record being set Saturday.
"This is what this race is known for," Chelanga said.
"But sometimes to break a record everything has to be really perfect. You never know what's going to happen in a race. It'll be cool but I can't promise anything."
Event organizer Hank Brown told News 5 WCYB Friday that 3,300 runners are currently signed up, and he is expecting over 4,000 runners by the 9:58 p.m. start time.
