Updated at 9pm

Athlete Diane Borg has made her seasonal best during the first round Heat 2 of the 100 metres sprint at the London 2012 Olympics. At 11.92s, she clocked in eighth. Borg also had the second fastest reaction time, at 0.155. The best time of her heat was clocked by American Carmelina Jeter at 10.83s.

Borg is currently standing at 53 out of 56.

Earlier, Borg clocked in third with 12s in the prelimanary heats, after Kaina Martinez of Belizie (11.81s) and Delphine Atangana of Cameroon (11.71s).

In sprint races, the time separating athletes can be as little as one hundredth of a second, requiring a photo finish.

A good start is crucial, as is technique while running and the quality of the finish. Diane Borg had the fastest reaction time at 0.164s.

The 100m is run along the home straight of the athletics track. The 100m competition starts with a preliminary round, which is limited to those athletes who have not as yet achieved the qualifying standards. The qualification procedure from this round is determined by the final number of entrants.

The competition then continues with heats. The number of heats and the number of athletes progressing to the next round depends on the number of athletes competing. In each heat the fastest athletes go through, as well as a set number of the fastest losers across all the heats. The following rounds run on the same format, until eight athletes are through to compete in the final.
