Organized by: Mammoth Endurance | Built for the Pursuit, Not Finish Lines.

General Race Format:
The goal of this event is to log as many complete triathlons, duathlons, or single laps (for run, swim or bike only events) in the allotted time. You may choose to race as a solo athlete or as a relay team. Choose from either a 12 hour or 24 hour race.

You and or your team will be assigned a "pit area" inside the Village where you setup camp for the duration of the event. This is where you sleep, eat, store your gear, etc.. - your home away from home.

You are not required to change disciplines in between each leg of the event. For example, you may bike 10 laps in a row, then swim 5 and then run 8. You can complete laps of any discipline in any order. Teams are not required to change athletes after each leg. For example, team member A can run 5 loops in a row, then bike 3 before handing off to team member B. However, teams may only have one athlete circulating the course at a time and must switch between team members inside the transition area.


Solo or Team Race Disciplines:
 - Triathlon
 - Duathlon
 - Aquabike
 - Ultra Run
 - Ultra Bike
 - Ultra Swim

General Course Information:
The swim takes place in a beautiful section of Oak Mountain State Park. The course is a .25 mile loop. The water here is great for swimming and sees a water temp of around 68 - 72 degrees at this time of year. The area you will be swimming is considered a shallow body of water with water depths no greater than 8 to 9 feet across the swim course. 

The bike segment is 10.50 miles long and boasts some butter smooth roads inside the park with wide shoulders on both sides. The route curves through the park and you'll be surrounded by towering pines the entire time. This is an outrageous and back route so you'll have plenty of company out there on course as you get to know your fellow racers. The course has a few climbs as well as a few fun descents (being it an out and back). This park is one of the best local training grounds for area cyclists & we get to enjoy the beautiful route for 24 straight hours! What more could you want! The park closes at night so there will be little to no vehicle traffic into the evening hours. It is HIGHLY recommended you practice some night riding before making your way to the event.

The 2 mile run course follows a unique route for this park. We start by running a short section of smooth, easy trail along the shore of the lake. After the turnaround, you'll run through the pit area and find yourself back on the paved roads and running again along the edge of the water. There is small elevation gain in the route, but it is considered a fast run course.
