Lined up in matching, sparkly spandex leotards, with their hair tied back in ribbons, one by one, the girls take off running down the mat, jump onto the vault and land perfectly on stacks of mats.
The fourth annual Crown of the Carolinas tournament brought 1,060 gymnasts to Rock Hill from eight states and two other countries to compete, said co-founder of Thomas Gymnastics, Mark Bonsky.
The tournament started at South Pointe High School's gym with about 400 athletes, and it has grown to the second-largest gymnastics competition in the state, behind a Clemson University tournament, Bonsky said.
At Winthrop University's West Center, during the three-day tournament, teams of girls competed in floor routines, tumbled on beams, vaulted onto mats and flipped over bars.
Never miss a local story.
Savannah Tetreault, 13, of York, said she enjoys tournaments like this weekend's because it allows for feedback from impartial, outside sources.
"I get to know what other people think of my routines, not just my coaches, who tell me the same thing all the time," she said.
She said she cleaned up with awards during the tournament, taking firsts in beam, bars, vault, floor and all-around.
"It feels good," she said. "It's nice to know that I can do what I set out to accomplish."
Savannah has been in gymnastics for four years and wants to keep going.
"I know I can get better as I get older," she said.
Carlee Shannon, 10, of Chester, said she has enjoyed her five years in gymnastics.
"I like doing things other people can't do," she said. "Like tumble on a 4-inch beam. It's scary."
She fell from that beam during the weekend competition, but she said it didn't hurt.
"I laughed," she said. "We were having fun."
Carlee said she finds backhand springs on the balance beam to be the most challenging.
"You have to jump in the air on the beam and land it," she said. "It's hard."
For someone who has been in gymnastics nearly all her life, 18-year-old Lauren Embry of Rock Hill said she's afraid of back handsprings during her routines.
"I've always been afraid of backwards tumbling. I think I'm getting old enough now that I think about what can happen," said Embry, a student at Westminster Catawba Christian School.
Embry said she stuck with gymnastics for 16 years because she wanted to finish what she started.
"I have always loved the sport my whole life. It's something not everyone else can do. I enjoy it," she said. "I feel that if I quit before I graduated high school, I'd be giving up."
Embry, like many of the athletes at the tournament, said the bars are her favorite.
"I've always been good with bars," she said. "It takes a lot of strength."
Ken Hammon brought twins Kenley and Kaitlyn to compete this weekend. The girls, who celebrated their 10th birthday Sunday, have been involved in gymnastics since they were 2 years old, he said.
"It's a busy weekend," he said. "I enjoy it; I like watching the competition."
Kenley and Kaitlyn agree that the bars are their favorite event to compete in.
"It's fun to spin around the bars," the girls said.
Lilly Lewys, 8, of Rock Hill, agrees.
"I like to jump from them," she said.
The Crown of the Carolinas Foundation is a nonprofit organization that hosts the event, Bonsky said. Profits from the competition help pay for $15,000 in scholarships to York County gymnasts.
It also funds a $1,000 scholarship for a Winthrop student with a background in gymnastics in the name of Thomas Gymnastics owner and Winthrop graduate, Sally Thomas.
The 47 teams netted a 25 percent growth in this year's competition from last year, Bonsky said.
"That's great, given the current economic condition," he said.
"The tournament gives local gymnasts the opportunity to compete locally," Bonsky said.
In addition to giving three York County teams an outlet, teams from Barbados, the Grand Caymans and seven other states spent the weekend in Rock Hill. Bonsky estimates the weekend brought $150,000 of economic impact to the area through hotels, restaurants and shopping.
