In order to give you a more precise answer, I went back and looked in Dr. Robert Rooks' book, "100 Years of Tomcat Football." According to Dr. Rooks, "an all-weather track was built around the football field in 1965. This was the first such track of any sort in West Tennessee outside of Memphis, and the first track of any sort in Haywood County. The estimated cost of this oval was $15,000. Most tracks are a quarter of mile long, but this track was a fifth-mile in length because there was not enough room for a larger one. As it is now, the north end of the the track is on the right-of-way of the railroad. Before the track was built, the football field was moved several feet to the west. This move allowed enough room to run the track to run in front of the east side stadium."
I apologize for the poor quality of the photo. If you notice the four outside corners of the end zones, the field comes up on the track. Those areas are raised to promote drainage. This photo was taken around 2012. Since that time, portions of the north and south ends of the track have been removed, but there are still some raised areas in the end zones.
