The CNN Fit Nation Lucky 7 get major props for finishing the Nautica Malibu Triathlon this weekend, and so does NASA astronaut Sunita Williams.

Williams did the swimming, biking and running events aboard the International Space Station using exercise equipment specialized for space. This makes her the first person ever to complete a triathlon in space.

"I'm happy to be done," she said after finishing her activities. "It wasn't easy, and I'm sure everyone out in California is excited to be done, too."

She said via NASA TV that her watch said it took her 1:48:43 for the three events and the transitions, although getting from one activity to another is a little different in space than for Earthlings.

Williams used the onboard stationary bicycle for biking and the space station's treadmill for running. There's no pool on the station, however, so she used a simulated weight-lifting system.

After finishing, Williams gave a shout out to CNN's Dr. Sanjay Gupta "who is really interested in health and fitness," she said.

Williams is currently the International Space Station Commander for the Expedition 33 crew.
