Jamaican sprinter Usain Bolt has said he is considering the possibility of continuing beyond the 2017 World Championships although his career will conclude this season.
Bolt, 30, had previously said his final race would be at the London Stadium in August, bringing an end to the most successful sprint career in athletics history.
However, Bolt appeared to leave his options open after revealing he had spoken with coach Glen Mills about whether the World Championships would indeed by his final event.
"We haven't fully made up our mind on what we're doing yet," he said on Monday ahead of the Golden Spike Athletic meeting in Ostrava, Czech Republic.
"I'm not worrying about that until the World Championships or at least getting close to it.
"Right now, I'm just focused on getting through the season.
"I just like entertaining the crowd. I definitely want to try and enjoy every minute of it - it won't be the same sat in the stadium."
Bolt is an eight-time Olympic champion having won gold in the men's 100 metres, 200m and 4x100m relay at Beijing 2008, London 2012 and Rio 2016. His 4x100m relay gold from Beijing was later stripped after Nestor Carter failed a doping test.
At Beijing, Bolt became the first man in Olympic history to win the 100m and 200m in record times. Nine of the fastest 30 times over 100m belong to Bolt, including three of the top four.
"It's just been a great career. I've really enjoyed the ups and downs, all the experience I've gathered, all I've been through, the happiness and the sadness," Bolt said.
"It's been a wonderful career and I've done everything I've wanted to do and it's coming to an end and I'm fine with it.
"It's an emotional season."
Bolt also reiterated that he would not be defending his 200m title in London.
"People keep asking, but no," he said.
