Runner's high: Tim Peake finishes London Marathon in space

British astronaut becomes first man to complete a marathon in space, finishing in three hours, 35 minutes and 21 seconds

The treadmill turned and the timer began. It was 10am on Sunday morning in London and as tens of thousands of runners set out on the marathon below, the British astronaut Tim Peake broke into his stride on board the International Space Station. He was somewhere over the Pacific Ocean.

Dressed in a red vest and black shorts, with the union flag hoisted behind him, Peake's run took him into the world record books as the first man to complete a marathon in space. He finished in three hours, 35 minutes and 21 seconds. In the time he had taken to pound out 26.2 miles, he had travelled more than twice around the planet.
