Uganda's Joshua Cheptegei has won 3 global 10,000 titles on the track but he's never won the Olympic 10,000. Can he get the job done in his final track Olympics? If not, is Jacob Kiplimo the new king or will it be one of the Ethiopians? Does Grant Fisher have a shot? *The 1st Olympic track gold will be given out on Friday - Who you got in the m10k? Cheptegei, Kejelcha, Barega, Kiplimo, Fisher?
