The KTC Expo races are (one of) the longest running events in Knoxville. There are a ton of recognized groups like Most Expo's Run, Mother/Daughter, Father/Son, and of course Age Group awards.
Having run this race as one of the first events to return in 2020, I would say there was a fantastic execution! The race was not held in it's normal location due to City guidelines but that didn't stop KTC from hosting a great race. The course was an out and back for the 5k, and a 2nd out and back for the 10k. One self-serve water stop at the half way point for the 5k made for 2 water stops for the 10k. One highlight of the 2020 version was that the course ended on a downhill.
While I did participate in an unusual running of this event, I would definitely suggest runners participate in the Expo.
