Dutch star Sifan Hassan won the Chicago Marathon women's title on Sunday in an unofficial time of two hours, 13 minutes and 44 seconds -- the second-fastest women's time in marathon history.
The 30-year-old Ethiopian-born runner set a course record. Her time was second only to the women's world record of 2:11:53 set by Ethiopian Tigist Assefa at last month's Berlin Marathon.
Hassan, who won her marathon debut in April at London, is the Tokyo Olympic champion at 5,000m and 10,000m and won medals at 1,500m and 5,000m six weeks ago at the World Athletics Championships.
