Sunita Williams became the first NASA astronaut to complete a triathlon in space after running, biking, and “swimming” along with athletes competing in the Nautica Malibu Triathlon. "I'm happy to be done," said Williams. "It wasn't easy, and I'm sure everybody in California's very happy to be done, too." Williams swam a half-mile, biked 18 miles and ran four miles finishing in a time of one hour, 48 minutes, and 33 seconds. She used the space station’s treadmill and stationary bike plus the Advanced Resistive Exercise Device to approximate swimming. Williams began training before arriving at the space station this July and ran a seven-mile race in space as part of her training. On her last stay at the space station, she ran the Boston Marathon on a treadmill finishing with the time of four hours, 23 minutes, and 10 seconds.
