LONDON (AP) — A British astronaut will attempt to become the first man 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.
