[1] The first day saw a number of high-profile athletes eliminated; Derrick Atkins, the 2007 silver medallist, did not pass the first round.

[2] Churandy Martina, area record holders Samuel Francis and Olusoji Fasuba, Simeon Williamson, and 2003 gold medallist Kim Collins were all knocked out in the quarter-finals.

Also, a double false start meant disqualification for the new European junior record holder Christophe Lemaitre.

Gay, Powell and Rodgers ended with the fastest times of the day, although Bolt and Bailey comfortably won heat five, exchanging smiles and glances in the process.

By the 20-metre mark, Bolt had already taken a slight lead of 0.01 seconds, and he continued to pull away from the rest of the pack until the finish.

[8] Bolt beat his own previous mark that he set when winning gold at the 2008 Summer Olympics in Beijing by over a tenth of a second, an achievement statisticians claimed was 20 years ahead of schedule in the long term scheme of the 100 metres world record progression.

[9] So emphatic was Bolt's winning time, that both bronze medal winner Powell and sixth placed Dwain Chambers said they were happy just taking part in the fastest race in history.
