Here is part 4 of Chasing Bolt. Thanks to the PUMA marketing team, we will have the other episodes over the next few days. Usain Bolt is the track & field athlete who has fans in all of the sports world. He can gather a crowd in Daegu, as well as Berlin, as well as New York. He is not merely a track star, he is a global sports phenomenon. Usain Bolt should show the track & field world what the sport can be, with a focus on the competition, and then the entertainment of great competition!
