Usain Bolt and Justin Gatlin have been the faces of Olympic sprinting for more than a decade.
Gatlin was the 2004 Olympic 100m champion. Then Bolt won a combined six sprinting gold medals at the 2008 and 2012 Games.
“When you think about track and field, you think about Gatlin and Bolt,” Gatlin said. “We are showmen. We are true competitors.”
2000 Olympic 100m champion Maurice Greene has watched Bolt and Gatlin push each other.
“If there’s not anyone there to challenge you, then everything is going to get stagnant,” Greene said. “It’s not going to get there.”
