No stopping Bolt, says Johnson
Four-time Olympic champion and American sprinting great Michael Johnson believes there's no stopping Usain Bolt once he remains healthy.
Johnson, who held the 200m world record (19.32) until Bolt ran 19.30 and then 19.19 at the 2008 Beijing Olympics and 2009 IAAF World Championships, respectively, added that he was amazed by the big Jamaican's ability to remain focused and motivated in spite of his dominance in the past six years.
"I think that for Usain Bolt, health is going to be his biggest issue going forward because as you get older, it becomes much more difficult to remain healthy, but I think he has done a brilliant job managing the amount of races he runs, and I think that's going to be key," said Johnson during a press conference at Atlantis in The Bahamas on Friday.
Bolt ran three races last year, including two relay legs at the Commonwealth Games, 16 individual races the year before, and 19 in 2012. This is compared to Justin Gatlin, who ran 21 individual races last year and 19 in 2013.
"I have said this many times before: There's no one that can beat him (Bolt) when he is at his best, but he has to be at his best," said Johnson, who also won eight World Championships gold medal.
The IAAF ambassador also spoke of his admiration of Bolt's ability to keep himself motivated after three world records, six Olympic titles, and eight World Championships gold medals.
"I marvel at his ability to remain motivated given that he is world champion, Olympic champion, and world record holder in all his events," he added. "It took me 11 years to do that, and he did all of that in the space of a few years."
