Astronaut to be first to run marathon in space

A British astronaut may become the first man to run a marathon in space. Tim Peake will run the 26.2 miles on the International Space Station (ISS), on a treadmill, at the same time as the London Marathon in April.

He is due to blast off from the Baikonur Cosmodrome, in Kazakhstan, on December 15, and will stay in space for 173 days, until June 5 next year.

When he does the marathon, he will be attached to the treadmill by a harness to combat weightlessness, and will be watching a video of the London course on a big screen.
