The Olympic Games are only seven days away and many are already starting to predict who the star athletes of this edition will be, especially in the Olympic discipline par excellence: track and field. With regard to the men's 100 and 200m sprint events, there are two top favorites: team mates Usain Bolt and Yohan Blake, followed suit by the Americans Tyson Gay and Justin Gatlin, in the 100m, and Wallace Spearmon in the 200m. Jamaica is also a big favorite in the relay events. For the 400m, everyone's bet is on the American LaShawn Merritt, who will however need to watch his back especially from the defending World Champion, Grenadian Kirani James. In the middle distance race, all eyes are on Kenya as the potential winning nation, with Rudisha in the 800m, and the pair Silas Kiplagat and Asbel Kiprop in the 1500m. In the 5000m and 10000m, there are great expectations from the Ethiopian athletes, with Somali-born British athlete Mo Farah as a likely candidate to win a place on the podium. In the 110m hurdles, all eyes are on the Chinese Liu Xiang and the American Aries Merritt; while in the 400m hurdles, the favorite is Puerto Rican Javier Culson, who will need to watch out especially for the British athlete David Greene.
