Three-time Olympic champion Usain Bolt has downplayed his lacklustre form ahead of London 2012.
The 34-year-old recorded the slowest 100m time of his career outside of qualifying rounds in Ostrava last Friday, but was untroubled by the result.
"Everybody has bad races. It's just one of those things in track and field. You can't win every race, and you can't come out and run fast every day," ESPN quotes Bolt as saying.
"We are humans and we have off races and it's just one of those things. This is sport. It happens in basketball and baseball and it happens to athletes. I'm never worried because at the end of the day it's all about the championships."
Bolt, who holds the world record over the distance, went on to say that he remains confident of securing victory at London 2012.
"I'm confident that myself and my coach can put together a programme to be a champion. I will focus on that. My coach is the greatest coach ever and knows exactly what to do to get me to the top," he added.
The London Olympics get underway on July 27.
