3 US 1500m Top Guns to Battle at adidas Grand Prix

A two-time Olympic gold medalist, a three-time World Champion, and the most dynamic young American track star in a generation are among the latest athletes added to the roster for the adidas Grand Prix on June 14, organizers have announced.

Mary Cain, who earlier this month turned 18, rewrote the record books last year by breaking high school and/or U.S. junior marks at eight distances—including 1500m—and becoming the youngest athlete ever to represent the US at the IAAF World Championships. So far in 2014, she has twice broken the World Junior Record for 1000m indoors, and won the U.S. indoor 1500m title.

Among the athletes Cain will face over 1500m is American Jenny Simpson, the 2011 IAAF World Champion. The last time the two met was in the final of the World Championships last summer, where Simpson won a silver medal and Cain finished 10th. Also in the New York City field is Morgan Uceny, a three-time U.S. champion who in 2011 was ranked Number 1 in the world at the distance.
