While other events have excitement, drama, record-breaking potential and name power, no event this summer has a more powerful combination of everything than the men's 100 meters.
For starters, the event itself is one of the most primal and exciting in all of sports—who can sprint faster than who.
Aside from that, however, is the presence of Usain Bolt—a man who was truly untouchable four years ago as he ran a time of 9.69 seconds, .2 seconds ahead of second place.
And that was while celebrating across the final 10 meters.
Adding to the excitement is Tyson Gay, the Americans' best chance at dethroning Bolt. In what is his final chance at gold, Gay is hoping to avenge a disappointing 2008 in which he didn't even qualify for the finals.
Finally to add even more drama is the presence of Justin Gatlin, one of the most fascinating figures in London.
Gatlin, the 2004 Olympic gold medalist, was banned from competing for four years. When his ban expired in 2011, however, Gatlin has come back strongly since, winning this year's trials over Gay with a time of 9.80 seconds.
