From Malaysia to Maryland, sport stackers from around the world gathered on Guinness World Records Day to set a new mark for “Most People Sport Stacking at Multiple Locations in One Day.”

They stacked in school gymnasiums, on playgrounds, in hospitals, libraries, and even at a horse shelter. Using specially designed plastic cups called Speed Stacks®, stackers raced against the clock, competed in relays and stacked in a variety of fitness activities for at least 30 minutes. The number to beat: 222,560. The record-setting count being submitted to Guinness stands at 276,053 representing 1,252 schools and organizations from 24 different countries. All 50 states in the US were represented.

"We hoped to reach a quarter million, and we cruised right past that," said Mark Lingle, Director of the World Sport Stacking Association, which organized the event. “Next year we’ll shoot for 300,000.”

The stacking action was part of the annual WSSA STACK UP! presented by Wonderful® Pistachios and Speed Stacks, Inc.

Stack-4-Mack The Days End Horse Rescue in Woodbine, Maryland was the site of some non-stop stacking where a group of dedicated home-schooled students raised $650 in pledges to support a favorite rescue horse, Mackie. They also landed a feature story in the Sunday paper and hope to expand their stacking service project to even greater heights next year.
