Jamaican sprinter Usain Bolt has said that he is looking forward to returning home after a long season on the track.
The 27-year-old ended with a win in the final Diamond League meeting in Brussels on Friday night.
Following the race, the six-time Olympic gold medallist said that years of domination are beginning to manifest physical problems.
"I remember going to my doctor and he told me I had to pay close attention to my back," Bolt told reporters. "I know I have to be more focused on staying in shape.
"The older you get the harder it is to come back from injury. I've got to stay injury-free during the season that's the main factor.
"I've been smiling ever since I came to the stadium because I knew it was the last one of the season. I'm just happy to be done and looking forward to going home."
Bolt scooped three gold medals in the recent World Championships in Moscow.
