The Diamond League, an annual track and field meet, will take place in Rome on Thursday evening, and the forecast may call for lightning.
Sprinter Usain Bolt, given the nickname Lightning for obvious reasons, will be the main attraction.
The world-record holder in the 100-meters and 200 meters, Bolt is seen as the favorite, but will be challenged by American Tyson Gay, who has the second all-time fastest sprinter in the 100 meters, and third all-time fastest in the 200 meters.
The Jamacian will also face off with former record holder and countryman Asafa Powell, who held the best 100-meter time for nearly three years. Powell set a world record of 9.74 seconds in Italy in 2007, but Bolt has broken the mark three times.
Bolt has struggled with an Achilles tendon injury, but contiues to state that he wants to be a legend in track and field.
The Diamond League event is seen as a tune up for the 2011 World Championships in Daegu, South Korea.
