One of the Olympics' signature sports takes place August 3-12 in London. Track and field, an original Summer Games spectacle that dates back to the Olympics of Ancient Greece, never fails to disappoint in delivering dramatic results.
The 2008 Beijing Games and World Championships that have occurred since give us an indication of who appears primed and ready for a gold medal push. However, nothing is guaranteed and a fraction of a second can cause competitors to plummet from a spot on the winner's podium and into the ranks of also-rans.
With so much at stake, the outcome of each event is tough to predict, but we do our best here. Highlighting ten monumental events in both men's and women's competition, we size up the top contenders and take our picks of who comes out of the fray wearing a medal.
