The new world record now is 47.04s. The old record was 47.10s, also by Jamaica.
France came in second with a time of 38.20s
Saint Kitts and Nevis took the bronze in 38.49s. What a surprise !!
The USA team did not finish after the 3rd runner, Darvis Patton, tripped while trying to pass the baton to the 4th runner, Walter Dix.
Congratulations JAMAICA !!!!
Have a nice day..
