David Beckham paid tribute to Usain Bolt with an Instagram post after the Jamaican ran his final 100m race on Saturday at IAAF World Championships. Bolt took bronze in 9.95 seconds behind Gatlin (9.92) and American silver medallist Christian Coleman, who clocked 9.94.
Trinidad & Tobago sprinter Kelly-Ann Baptiste lined up in the women's 100-meter final at the IAAF World Championships in Athletics for the third time in her professional career Sunday and turned in an eighth-place finish while clocking 11.09 seconds in the final event of the night at the London Stadium.
"But he is eligible to be here", Coe, the head of the sport's governing body, told the BBC. I thought Usain was very generous with the observations he made. The fundamental reason for putting any substance on the banned list, she said, is that is has "an actual or potential performance benefit".
The American sprinter has been caught doping twice in his career, serving a total ban of five years.
Gatlin was banned for two years in 2001, after failing a dope test for amphetamines found in prescribed medication he had been taking since a child for Attention Deficit Disorder. The original length of eight years was halved following an appeal.
The second ban, a positive test in 2006 for testosterone, was reduced from eight years to four.
Coe reiterated his support for life bans for convicted drug cheats, but used Gatlin's example to illustrate how legal systems worldwide have frustrated efforts to impose more severe punishments.
The return of Justin Gatlin to top-level athletics removes the incentives for his fellow competitors to stay drug-free, says a former director of ethics and anti-doping at UK Sport. "One got watered down, which made it very hard for the second ban".
"So would I (like to see lifetime bans) and so would the majority of our sport", Coe said.
