Six-time Olympic gold-medal sprinter Usain Bolt will definitely be running in the 2016 Summer Games in Rio de Janeiro, Brazil, but retirement may be beckoning soon thereafter.
In an interview with BBC Radio 5 live (via BBC.co.uk) Thursday, Bolt discussed his future plans and indicated he's torn about competing in the 2017 World Championships, per NBCSports.com's Nick Zaccardi:
I really want to run at London, but I think the sport is not as fun as it used to be...It's more taxing. I can't enjoy it as much as I want to because I have to be sacrificing a lot more, so, uh, it's 50-50, I'm telling you. [...] After Rio, as I said, my sponsors want me to go one more year, but my coach said, "Listen to me, if you're not going to be serious about going to the World Championships in London," then I shouldn't do it.
Bolt burst onto the scene in 2008 in Beijing when he won both the 100- and 200-meter gold, along with the top prize in the 4x100-meter relay. The Jamaican superstar replicated those feats in London during the 2012 Summer Olympics.
Returning to the city where he backed up the hype at the most recent Summer Games would be a fitting conclusion to Bolt's career. The rigors of training and maintaining elite fitness will also be more taxing for the 29-year-old, though, and that seems to be weighing heavier on him based on his Thursday interview.
All indications are Bolt is going to at least end his Olympic career with a bang. American Justin Gatlin was considered a threat to knock off Bolt at this year's World Championships in Beijing, but Bolt got the better of him, winning the 100-meter and 200-meter races.
That brings Bolt to 10 World Championships gold medals. He doesn't have much else to prove in such races, but he also looks primed to sweep them for another year if he so desires.
