But even Kimetto, with his giant heart and ostrich legs, still fell well short of a barrier long thought impregnable, at least for this generation of athletes: to run a marathon in under two hours. Today, after two years of preparation and research, Nike is announcing a project called Breaking2 that has a single goal: to break the two-hour mark in a special marathon planned for the spring of 2017. If the attempt is successful, it will be the most significant moment for running since Roger Bannister’s first sub-four-minute mile in 1954. Nike calls the project its “Mission to Mars,” and its team of designers, scientists, coaches, and statisticians believes that on a specially designated course in an as-yet undetermined location, it can propel at least one world-class athlete, and possibly three, to shave three percent from Kimetto’s world 968重庆之声每周一至周五8点56分每天三分钟养成良好英语听说习惯
