Wipeout Run, Brooklyn

ROC Race—or Ridiculous Obstacle Challenge Race—lets participants step into the soaking, sudsy running shoes of a game-show contestant. At locations across North America, runners dash through an adventure course peppered with oversized obstacles. Look for slides slicked with soap suds, padded wrecking balls, and steep inflated slides, to name a few. After a gauntlet of swings, jump balls, climbing walls, and the Foam of Fury comes the soaking-wet grand finale: runners zoom to the finish line down a four-story water slide.
