The Big Nasty Mud Run x4 is poised to be as big as ever.
"We've got about 1,300 signed up," said Dan Pavlin, a volunteer organizer.
The race organizers expect to turn out at least 1,500 by its start on Sept. 22.
"There's five miles, 30 obstacles," Pavlin said. "We've got a ton of mud pits in different forms and fashions."
Hosted by the Fellowship of Christian Athlete's Endurance Sports Ministry, the event is one of the largest mud races in the area and boasts more than just competitions.
It supports Kicklighter Resource Center, Godesign, Habersham School, JROTC and Performance Initiatives, who have helped to organize and run the event with a staff of volunteers.
While racers can participate in either male or female competitive waves, individually or with teams, there are also opportunities for the casual thrillseeker or child.
"It's challenging, but we have found a majority of the people that run the race aren't competitive runners, they're just people who want to have fun," Pavlin said.
Two children's waves will take place in the early and late morning, and participants can run with or without a parent at their side, followed by several individual and team runs throughout the morning.
"This one is really awesome because there's a lot of trail running," said Aimee Beatty, a yoga instructor and paralegal who placed first last year. "It's a run that you can do individually or in a group. A lot of people just run it for fun, just to finish it, just to test themselves."
Wave 15 holds a more special meaning than others.
A team has dedicated Wave 15 in honor of Shana Crozier, who passed away late this summer in a boating accident. Crozier competed in last year's event.
"We're basically just getting everyone together to do something she loved doing," said her sister, Sheri Nicole Hughes. "It's to remember her by."
