Bolt, along with compatriot Yohan Blake, lead a Jamaican team set to continue its thrilling Olympic showing. Jamaica has collected 10 medals in London, all coming from the men's and women's track and field.
The stiffest competition comes from Team USA, which broke a 4x100 meter team record in the preliminaries with a 37.38 time. The previous record of 37.40 was set by the Carl Lewis-led squad in the 1992 Barcelona games.
Justin Gatlin will run the anchor leg for the U.S., who has been trumped by the Jamaicans at every turn during these games.
''We're going to figure out a way to go out there and compete with them,'' Gatlin said to the Associated Press. ''We're not scared of them.''
Bolt, the world's fastest man, did not run in the preliminary races, and is replacing sprinter Kemar Baily-Cole at the anchor spot. Jamaica set the Olympic record in the 4 x 100m relay in Beijing with a time of 37.10, but Bolt ran the third leg in the 2008 race.
If successful, Bolt will have repeated his gold winning ways in all three of his events from Beijing.
Prediction: Jamaica (G), USA (S), Trinidad and Tobago (B)
