Getting covered in mud is a big part of obstacle races like Warrior Dash. So, faucet company Delta set up a giant product demonstration after Saturday's event in Indiana—and claimed the Guinness World Record for most people showering simultaneously.

Some 331 runners, including 1992 Olympic gold medalist and television personality Summer Sanders, helped Delta cinch the title in Crawfordsville. The previous record was apparently held by Thailand's 12Plus Shower Cream, which got 300 people wet at Dor-Shada Resort in Pattaya. (Yes, offbeat world records seem to exist primarily to add an air of legitimacy to marketing stunts.)



The activation, part of Delta's "HappiMess" campaign, was created with help from sports marketing firm Revolution and media agency Spark. It's a pretty clever place for Delta to show up—but it's nowhere near as hard-core as Reebok bribing runners in another adventure race to get giant tattoos of its own triangle-shaped "delta" logo.
