But even if they aren't, South Sudanese athletes will still be able to compete under the Olympic Flag, as Guor Mading Maker did in the marathon at London 2012.
Maker was awarded a scholarship by the IOC which the South Sudan federation said he had to hand over to them (to distribute among all athletes) and have suspended him until he does.
Maker ran at London 2012 as an "Independent Olympic Athlete" and is now a US citizen, but hopes South Sudan will be recognized by the IOC for 2016. In the meantime, he is seeking support for himself and other South Sudan runners via crowdfunding.
Chemtai won a close race over Nelson Oyugi (1:03:31). 2012 Olympian Guor Maker ran 1:05:52.
Jen Rhines and Guor Maker were the top Americans.
