Usain Bolt is targeting a first ever sub-19 seconds 200 metres as he homes in on an unprecedented sprint three-peat at the Rio Olympics.
The 29-year-old Bolt has also suggested he might not stop there, leaving open the chance he could extend his career beyond the 2017 season he has previously said would be his last.
After a slow start to 2016 due to ankle problems, Bolt said he was getting back on track toward repeating his sweep of the 100 and 200m golds at the last two Olympics and the gold in the 4x100 relay he also win in 2008 and 2012 with his Jamaican team mates.
"Just to defend my titles, to do the three-peat. That's my main goal. That's my main focus," Bolt said in New York on Tuesday. "My secondary goal is to try and run sub-19," added Bolt, who set the world 200m record of 19.19 in 2009. "That's something I really want and I hope that everything goes smoothly and I can get it. That would be a big step for me."
Bolt said he has been gradually rounding into shape.
