London 2012: 3 Sprinters Who Will Challenge Usain Bolt for World's Fastest Man

Usain Bolt currently holds the title of World's Fastest Man.

In the 2008 Olympics, Bolt dominated the sprint events, winning the 100-meter dash (9.69 seconds), 200-meter dash (19.30) and helped his 400-meter relay team win the gold medal (37.10).

Now, it's the 2012 Olympics and Bolt will be challenged as the top sprinter in the world.

But, who?

Here's a look at three sprinters who will challenge Bolt for the title of World's Fastest Man.

3. Asafa Powell

The Jamaicans have three strong sprinters representing them in London.

Powell is the lowest on the totem poll of the three, as he's not expected to best his countrymen.

But, he has it in him to do so.

Powell will be on the Olympic stage for the third time in his life, but has only found success in the relays.

With his time being a major sprinter on the world stage coming to an end, he'll lay it on the line to see if he can become the best in the world.

If he does so, it will be considered a major upset.

But, it could definitely happen.

All it takes is the perfect race.

2. Justin Gatlin

Everyone remembers Gatlin from the Athens Olympics.

He won gold in the 100, bronze in the 200 and helped the U.S. 400-meter relay team win silver.

Then, in 2006, Gatlin was informed that he tested positive for performance-enhancing drugs. Although, he claimed his innocence, Gatlin was banned for four years, avoiding a lifetime ban in exchange for his cooperation.

Now, Gatlin is back on the world stage and is ready to once again claim the 100-meter title.

His 9.80-second performance at the Olympic Trials has shown that he is to be considered one of the best sprinters in the world.

If he does indeed win a gold medal in the 100, he will become only the second man (along with Linford Christie in 1992) to win a 100-meter dash Olympic gold medal over the age of 30.

Right now, he looks like America's best hope for gold in the 100.

1. Yohan Blake

While not a complete unknown prior to the Jamaican Olympic Trials, not many people outside of the country had heard of Blake.

But, over the last few years, Blake has made a name for himself on the track, winning the 100 in last year's world championships, as Bolt was disqualified.

Then, Blake upset Bolt in both the 100- and 200-meter races at the trials, putting his name on the map with those who only follow track every fourth year.

Blake made a statement to Bolt that he was coming for his title of World's Fastest Man. And, honestly, he could be that one that unseats Bolt.

If anyone can do it, it's Blake.

He's done it before and I believe he'll do it again.
