Sunday marks the third day of track and field at the London Olympics and Jamaican sprinter Usain Bolt attempts to defend his 100-meter title against countryman and rival Yohan Blake.
Bolt captured the world's attention with his gold medal run in the men's 100 at the 2008 Beijing Games. Bolt also won gold in the 200m and 400m relay four years.
In addition to Bolt's greatness, over the years there has been a growing rivalry between Bolt and Blake.
Blake has come onto the scene in recent years to steal some of his compatriot's thunder. Blake won last year's world title in a race that Bolt was disqualified from for a false start.
Blake also beat Bolt in both the 100 and 200 at the Jamaican Olympic Trials.
In addition to the duo of Bolt and Blake, the American sprinting trio of Tyson Gay, Justin Gatlin and Ryan Bailey will also be in the men's 100 final.
Bailey recorded the fastest time in qualifying Saturday at Olympic Stadium, equaling his personal best with a run of 9.88 seconds.
Track and field medals will also be awarded Sunday in the women's marathon, triple jump and 400 meters, while the men also will battle for gold in the 3,000m steeplechase and hammer throw.
