According to the Guinness Book of World Records, Audrey Mestre Ferrera of the Canary Islands holds the record for the deepest free dive on a single breath. The depth? An amazing 411 feet (125 m). The dive lasted just over 2 minutes. In related breath-holding news, here’s a video from AllDumb.com that shows a guy who swam 166m on a single breath in a swimming pool. Good gills on these two.
