Few weeks before the Games, Grenadian athletes trained at Broadbridge Heath Leisure Centre near Horsham, West Sussex.

Grenada Olympic Committee sent the nation's largest delegation to the Games, with a total of 10 athletes (6 men and 4 women), competing in 4 different sports.

Taekwondo jin Andrea St. Bernard, who competed for the nation's Olympic debut in her sport, was the oldest athlete of the team, at age 32.

Track runner and world junior champion Kirani James, the youngest athlete at age 19, was Grenada's flag bearer at the opening ceremony, and subsequently, became the nation's first Olympic medalist when he took the gold medal in the Men's 400 metres.

Beckles did not start the race, so she didn't progress to do the heat Esau Simpson was the sole Grenadan participant in the 2012 Olympic Men's 100 metre freestyle.
