作为泳池中距离最长的比赛，1,500米自由泳是考验选手耐力的一块试金石。孙杨此次打破了自己去年在世界游泳锦标赛上创造的14分34秒14的世界纪录。在去年的世界锦标赛上，孙杨打破了澳大利亚游泳名将哈克特(Grant Hackett)保持了10年之久的纪录。
As a race over the longest distance in a pool, 1,500 meter free style is a touch stone that tests the stamina of swimmers. This time Sun Yang breaks the record of 14m34s created by himself at the world tournament last year, whereas before that the record by Grant Hackett had been there over ten years.
