British astronaut to run a marathon in space

LONDON (AP) _ A British astronaut will attempt to become the first person to run a marathon in space, as part of his 173-day mission to the International Space Station.

Tim Peake will run a digital version of next year's London Marathon on a treadmill as the ISS orbits the earth, at the same time as more than 37,000 people run in the race on the ground.

To combat weightlessness, Peake will wear a harness that tethers him to the treadmill as he runs. He will watch a video of the London course on a big screen in front of him.

Peake says ``the London Marathon is a worldwide event. Let's take it out of this world.''

The London Marathon is on April 24.
