It is too bad that people in Korea are going to miss out on seeing one of the greatest sprinters, if not the greatest ever to run in track & field:

World and Olympic sprint champion Usain Bolt has canceled races in China and South Korea later this month and decided to bring his season to a close because of fatigue, the Jamaican said on his website on Friday.

The triple Olympic and world champion was scheduled to run 100 meters races in Shanghai on September 20 and Daegu on September 25 after competing in a 200 meters at the world athletics final in Thessaloniki, Greece this weekend.

“I have been suffering from fatigue from as early as the Zurich meet and after careful discussions with my coach and management team, even with medical advice, we felt it necessary to close the season,” read a statement on www.usainbolt.com.

“The season has been long and has been challenging with early challenges I faced. In addition the risk of injury becomes greater and if I compete in the shape I am in, I may be at great risk,” he added.  [Reuters]
