Get ready to toe the line at 9:00 AM for this Knoxville event offering three distances—grab your bib at packet pickup (starting 30 minutes before the race and wrapping up 10 minutes before start time) near Shelter #1, and note that all registration must be completed on RunSignup with no day-of sign-ups available. The 5K and 10K share an out-and-back loop structure, with the 5K runners completing it twice and 10K participants tackling it four times, while half marathon runners will loop the longer out-and-back course six times. All runners have a 3-hour-30-minute time limit to cross the finish line.
