NASA astronaut Sunita Williams has completed the first triathlon in space, running, biking and "swimming" along with athletes in the Nautica Malibu Triathlon held in Southern California over the weekend.
"I'm happy to be done," Williams said from the International Space Station Sunday (Sept. 16) after she crossed the orbital finish line. "It wasn't easy, and I'm sure everybody in California's very happy to be done too."
Sunita Williams is the U.S. commander of the Expedition 33 crew aboard the space station, which is orbiting Earth about 240 miles (386 km) overhead. She used exercise equipment, including a stationary bike, treadmill and strength-training machine specially formulated for weightlessness, to simulate the triathlon experience in space.
