4x100M RELAY
Jamaica has won every major sprint relay title on offer since Usain Bolt’s ascension in 2008 and are the fastest on paper again
THERE is no questioning Jamaica’s speed, so if the 2008 and 2012 Olympic champions can get the baton round safely, they are favourites to retain their title. The Americans dominated this event in the past and, based on the 100m times of the squad, they should be the closest challengers.
