Robert Cheruiyot of Kenya and Russia's Lydia Grigoryeva may have won the men's and women's titles in this week's Boston Marathon, but Sunita Williams is the champion of weightless division. The 41-year-old astronaut, who grew up near Boston, was harnessed to a treadmill at the International Space Station, hovering more than 200 miles above the earth.
Traveling at 17,500 miles an hour at zero gravity, with two laptops displaying the actual race, Ms. Williams finished her treadmill run in four hours, 23 minutes and 46 seconds. During that time, she also traveled around the world, almost three times. Just like runners on the ground, Ms. Williams received support from the crowd.
Her crewmates provided snacks of orange slices and the folks at mission control offered encouragement. At the 20-mile mark, they radioed: Keep it up. But I think you're over Heartbreak Hill.
