Can the seventh annual Herb Parsons Trail Marathon and Half Marathon top the sixth annual race? Of course!!! The seventh annual race is set for Sunday, January 5, 2020. The faster new loop course was well received at the 2019 race. Small tweaks to the course might make it even more fun-to-run in 2020. The marathon starts at 8:00 AM, and the half marathon starts at 8:30 AM. The race takes place at Herb Parsons Lake located in Fayette County TN about 45 minutes from downtown Memphis.
