I have participated in this race 4 times since 2013. This is my favorite course and half marathon. It is rural and small (1,100 or so) and only a half marathon.

My profile- I am a male, early fifties, 5'11" about 180 lbs. I can hold about an 8 MM pace for a half marathon.

Favorite parts-
The course. It is all on rural roads in central Tennessee and in the spring when things are just starting to green up. There is traffic on most parts of the course, but it is light traffic. The last 2 miles one lane is coned off for the runners. After about the first 1/2 mile, the road is never crowded with runners, so it is easy to go at your own pace.

Elevation- The course has slight rolls in the first 3 miles. Starting at mile 4 is the ascent up Whisky Hill. It is about a mile long and gets very steep at the top. You stay on top of that ridge with another tough hill at about 6.5 miles. Finally after another uphill at mile 8, the rest of the course is a gradual downhill. This allows for a strong finish.

This year they added a nice wrinkle and timed the mile long ascent up Whisky Hill for a "King of the Mountains" competition.
Weather- All the years I have run, the weather has been exactly what I like. Race starts at 8 am. The morning low has been about 35-40 deg, warming up to about 50 by the end.
Swag- The event is sponsored by Jack Daniels, so the swag is excellent (no whisky, unfortunately). There is a hat or visor, long sleeve tech shirt, and SwiftWick socks that have the event embroidered. The "medal" is engraved wood, which is unique.

Organization- The information before the race is communicated quite well. The parking is limited and there are just a few hotels close by. I am about 90 minutes away, so I drive in race morning. The event starts in the local park, which hosts most of the parking. There is an overflow lot, about 1/2 to 3/4 mile away. I have not used it, so I am not sure about the transportation.
Packet pickup is easy to do the morning of the event. There are lots of volunteers to it moves quickly. You get your bib and the long sleeve shirt then. Remaining swag you pick up after completing the half.
The start line is on a narrow 2 lane street, so that helps to spread out the start.
They use chip timing, so no need to rush to the front.
On-course- The course is well marked.It is all on blacktop roads that are reasonably maintained. The aid stations are well manned. Only water and gatorade. I believe there are 5 or 6 water stations, so that is a reasonable interval.
There are not many spectators on the route. The last 0.1 miles to the finish line have a loud crowd for that final kick.

I ran my 2nd fastest half marathon this year on this course at 1:46! All miles were sub 8 except for mile 5, which was close to 10 minutes.
