Before she started college, runner Morolake Akinosun made a bold prediction: That someday she would make the US Olympic team.

Lo and behold - five years later - she has made that dream a reality. On July 30, she took to Twitter again, linking back to that 2011 tweet and sharing a few updates on her progress: "It's 2016. I graduate from Texas in December. I'm going to the Olympics next week," she wrote.
