Jamaica, after three days of competition at the games of the 29th Olympiad, are sitting atop the track & field medals' table.

Adding to the historical feats of Usain Bolt's 9.69 world record in the men's 100m final and Shelly-Ann Fraser's 10.78 stunner to take the women's 100m, Jamaica's top position, at least for now, is another first time achievement.

So far, after 11 finals, Jamaica have two gold and two silver medals, on par with the experts predictions at this stage.

Sherone Simpson and Kerron Stewart, in a dead-heat 100m final, are the silver medal winners.

Russia with two gold, one silver and a bronze; Ethiopia with two gold and a silver; Ukraine with a gold and a silver and Cameroon behind Francoise Mbango Etone's (15.39m) triple jump success, rounded off the top five teams at this stage.
