An American astronaut set a new record by running the first marathon in space! Sunita Williams completed Monday’s 26.2 mile race aboard the International Space Station in four hours, 23 minutes and 46 seconds. She was taking part in the Boston Marathon, which took place on Earth at the same time. She had signed up for it before she went into space. Sunita ran the race tied to a treadmill with elasticated ropes to stop her floating away. For the marathon, she wore a bib with race number 14,000 and followed the progress of the Earth marathon watching a laptop. During the time it took Sunita to run the race, she circled the Earth twice.
