Revenge of Morpheus

Thirty-six-year-old American adventure racer Rebecca Rusch, whose Team Montrail won the gruelling 2003 Raid Gauloises [a multi-sport event], says three hours of sleep a day for a weeklong race is common. As are hallucinations: she once conjured up a Vietnamese fruit stand in the middle of a New Zealand field and was so convinced of its existence that she asked her teammates if they had any money. Instead of wasting time trying to convince her it wasn't real, they just told her they were broke. "Oh, OK," she said, and kept going.
