About the race
Viper 200 is another race by the Mamba Trail Runners which is famous for the Mamba 100 held in November. Viper 200 has 4 different race options. A 200 miler, 100 miler, 100 mile relay (teams of 4) and a 53K. The course is a 33.3 mile loop that travels all around the beautiful Shelby Farms Park dirt and paved trails. The dirt and paved trails are surrounded by tall, beautiful trees as well as the open air breeze off many lakes including Hyde Lake, the main lake at Shelby Farms. Not only are the trails beautiful, but you'll run past a herd of Buffalo that live in the park. You'll see numerous deer and other wildlife all throughout the course. The deer are very friendly and see visitors everyday so don't be surprised if you come very close to one as you run your race.
The race will give out Incredible swag to all runners. 200 mile runners will receive a hooded puffer jacket with the Viper 200 logo on it, while the 100 milers and 53k will receive a fleece long sleeve shirt with the Viper logo on it. All runners will receive a race short sleeve t-shirt.
The start/ finish line will be at the Agricenter Show Place Arena area. Here, there is lots of parking for crew, family, and friends. There is also RV Camping within walking distance to the Start line. This area is perfect for your crew to stage or set up your personal aid station. The aid station at the Start/Finish line is inside a building with public restrooms and showers. We will have a sleep station set up here that will be a tent with walls set up outside. Depending on the weather, we will climate control the tent with heaters or fans. We will provide cots with pillows and blankets for the runners to sleep. Tour de Wolf Aid Station will also have the same set up for a sleep station. We will provide a tent, with cots, pillows, and blankets for the runners. You'll hit the Tour de Wolf aid station twice in a loop. You'll have the opportunity to sleep three different times during a 33.3 mile loop. We encourage runners to only sleep at designated sleep stations.

100 mile relay race
The 100 mile relay race will start on Friday night April, 4th with teams of 3 runners. You have the option to have a 4th runner (ghost runner). If you have a team of 3 then each runner will run 1 loop (33.3 miles) and the exchange will be at the start/finish line aid station. The first runner of the relay team will check-in for the team and start the race. The other runners are not required to be there until it is their time to start. This means you may start your relay run for your team at 3 am or any other time during the night or early morning hours.
Teams of 4 will have the same set of rules that the teams of 3 have. Except you can have a ghost runner that can pick up any runner at the Tour de Wolf Aid Station. The ghost runner can run the Tour de Wolf trail loop or they can run from the Tour de Wolf Aid Station back to the finish line. If they run from the Tour de Wolf Aid Station back to the finish line then the previous runner becomes the Ghost runner.
There course is divided into 3 parts, Start line to the Tour de Wolf Aid station (12 miles). Tour de Wolf Aid Station back to the Tour de Wolf Aid station (11 miles). Tour de Wolf Aid Station back to the finish line (12 miles). The ghost runner can only run part 2 or part 3 only. The main runner must run 2 parts. So, if the ghost runner runs the last part, then the main runner must run part 1 and 2.
If the ghost runner runs the last part then the previous runner become the ghost runner for the next runner.
The relay race is all based on honor system. We will not give out buckles to the relay runners but we will give out a winning prize to the winning team. Relay teams can be all male, all female, or Coed. We will give out a winning prize to each category.

Pacers, crew and gear
Pacers will be allowed for 200-mile and 100-mile runners. No pacers for 100-mile relay or 53K runners.
Pacers can only start from the Start/Finish line Aid Station after loop 2. This is at 66.6 miles.
Pacers cannot carry anything for their runner (no muling), nor can a pacer run ahead of their runner to an aid station. Pacers must stay with their runner at all times. If the runner drops, then the pacer drops with them.
Crew: The crew will be able to access their runner at the Start/Finish line Aid Station and the Tour de Wolf Aid Station. No crewing at any other spots along the course. You are welcome to cheer and encourage your runner along the course as there are many places to set up and cheer. If a runner is caught receiving assistance other than the Aid Stations, then it will result in a Disqualification.
Gear: Average Highs and Lows in Memphis at this time of year is 70/50. But like most places in the Spring we could get cold fronts with storms which can cause the temperature to drop. Plan accordingly. Road shoes are perfectly fine for this course, but it would be best to have a set of trail shoes too.
Trekking poles are allowed.
