Eight well-balanced athletes will descend on the Central Park bandshell Saturday to compete in the World Championship of Slacklining.
The sport was started by a bunch of rock climbers out west back in the 1970s.
"On their rest days they would string up a one inch piece of webbing and they would Slackline to pass the time, and then it developed into the sport you see today, the two inch flat piece of webbing," Kevin Beaudoin of Gibbon Slacklines.
"It's in backyards all across the country and it's like the next best thing for your barbecue. Everybody is starting to get into it and it's like an exciting time for the sport," said Josh Greenwood, a Slackline athlete.
The Slackline competition is part of Adventures NYC, a free event features kayaking, biking, rock climbing, and more. A second day was added on Sunday at Marine Park in Brooklyn.
Visitors can take turns themselves, or watch the professionals do it.
Organizers say they hope to inspire people to get outside and go on an adventure.
"It's really a chance for really New Yorkers and visitors to come out and adventure our parks. We have stand up paddling, we have kayaking, we have Adidas coming in for rock climbing, there's so many exciting things to do," said Parks Commissioner Mitchell Silver.
