You could call it an unfair advantage. As tens of thousands of runners start the London marathon on Sunday, another competitor will take up the race unencumbered by endless queues for portable toilets, moving at 17,500mph high above their heads.
But there is nothing unfair about Tim Peake’s marathon plans. The British astronaut who arrived at the International Space Station four months ago will run the 26.2 mile course on a treadmill in a cramped room. How cool is that!!
