Astronaut Tim Peake Completes London Marathon in Space

Astronaut Tim Peake did something only one other person has ever done before: completed a marathon in space.

Peake, who trained for months, completed the London Marathon in three hours, 35 minutes and 21 seconds while being strapped to a treadmill at the International Space Station. After his run, the Guinness Book of World Records confirmed that Peake had set a world record for fastest marathon in orbit.

NBC News tweeted a video of Peake during the marathon.

Reportedly, the International Space Station passed Earth multiple times while Peake was doing the marathon. He was able to digitally participate in the race using RunSocial, an interactive running app that recreated the event.

Peake is the second man to complete a marathon in space. In 2007, Astronaut Sunita Williams completed the Boston Marathon in space in four hours.
