Astronaut
The British astronaut Tim Peake will attempt to run the London Marathon in space. On 24 April 2016, he will run 26.2 miles on a treadmill aboard the International Space Station (ISS), the same day as more than 30,000 runners will take part in the London Marathon. He will be only the second Briton in space after Helen Sharman in 1991. He will be the first Briton on board the ISS. Earlier, NASA astronaut Sunita Williams ran the Boston Marathon on board the ISS in 2007.
