Tim Peake has run the distance of the London
Marathon on a treadmill in the International Space Station (ISS).To neutralize the effects of weightlessness, he is using special equipment to keep him on the running belt. He ran the 42km (26.2mi) distance in about three hours, 35 minutes.
The ISS circles the Earth at the relative speed of 28,800km/h (17,900mph), so Major Peake covered more than 86,000km (53,000mi) during his run.
Major Peake started at the same time as the other runners: 10:00 on 24 April.
