Sunita Williams, the Indian American astronaut made headlines last week for becoming the second woman in history to command the International Space Station. She also holds the current record for maximum hours in space walks. However it obviously wasn’t enough because she set her mind to creating yet another first record for space.

She completed a triathlon in space by running, biking and even “swimming”  with athletes during the Nautica Malibu Triathlon held in Southern California over the weekend. She used used exercise equipment that included a stationary bike, treadmill and strength-training machine specially formulated for weightlessness to simulate the triathlon experience in space.

Running and cycling one can imagine, even if its done in gravity less space, but how did she swim? To simulate the swimming portion of the race, Williams used the Advanced Resistive Exercise Device (ARED) to do weightlifting and resistance exercises that approximate swimming in micro-gravity.Talk about advanced science projects.

At the end of the triathlon Sunita Williams thanked the astronaut strength and conditioning folks back in California for all their help. She stressed the importance of health and fitness of astronauts who took on long-duration spaceflights. Williams finished the triatholon with a time of one hour, 48 minutes and 33 seconds.
