Just weeks after a group of Charlotteans set a world record by doing 100 successive 5K runs in under 31 hours, another is vying for an equally unusual record in local swimming pools.

The World's Largest Swimming Lesson.

Not in one pool, mind you.

This no-cost affair will be worldwide, with pools around the world coordinating to do a beginner lesson at the exact same time: 11 a.m. on June 14.

In Charlotte, the YWCA, Ray's Splash Planet and Charlotte Aquatics are recruiting participants in hopes of getting a combined 225 students.

The goal of the event, which is coordinated by Disney World in Orlando, is to break the previous record of 3,971 students in 34 states, five countries and three continents. That was set in 2010, the first year of the event, which did not include the three Charlotte sites.

This year, nine pools in North Carolina are hosting lessons, and at least three in South Carolina.

It's estimated as many as 25,000 people will participate, including swimmers in Argentina, Bahrain, Lebanon, Peru and Greece.

Among the Charlotteans who'll be at the YWCA are Mity Fowler and her three kids: twins Carson and Morgan, 8, and son Jackson, 6.

All three know how to swim, but that's not the point, says mom.

"They are intrigued by the idea of participating in something for the Guinness Book of World Records," says Fowler, a former lifeguard.

"There's something about it that still appeals to kids, even today. I'm not sure if it's the unique nature of stunts people around the world pull to get recognition or something else."

Organizers say it's expected that many in the pool on June 14 will be skilled swimmers. Still, each site will teach the exact same beginner lesson for about 45 minutes.

This includes everything from why you shouldn't drink the water to how to float on your back.

YWCA officials say the record attempt is actually a well-disguised pitch for water safety, at a time when drowning is the second leading cause of accidental death for kids ages 1-14.

"I'm sure it will be slightly chaotic, but fun," said Andrea Greene of the YWCA. "And I hope we impress upon everyone that swimming is a life-saving skill."

Coincidentally, there's no guarantee a world record will actually be set June 14 or that someone might not come along and break it in no time.

That's what happened to the Charlotte Running Club, which had Guinness ambitions when it got 100 people to do successive 5K runs on March 27.

They did it in 30 hours, 56 minutes and 49 seconds.

Then, last weekend, the Greenville (S.C.) Track Club did it almost an hour faster.

Enjoy it while you can, guys. The Charlotte Running Club is considering its options.
