Triple Olympic champion Usain Bolt aims to "amaze" the world at London 2012 by running 9.4 seconds for the 100m and 19 seconds for the 200m.
Jamaican Bolt, 25, is the reigning Olympic champion and world-record holder over both distances, with times of 9.58secs and 19.19secs.
"People are looking forward to me running 9.4, 19 seconds, anything that's amazing," Bolt told BBC Sport.
Bolt's 9.58secs 100m world record was set at the 2009 World Championships in Berlin.
He told BBC1 programme 100 Days To Go that more performances, such as the ones that saw him take three gold medals at the 2008 Olympics in Beijing, would make him "a living legend".
"They want to see my personality, me enjoying it and doing crazy stuff, but they also want to see that time," he said.
"If I dominate the Olympics, I'll be a living legend. A living legend walking around. Sounds good.
"I'm working as hard as possible so I can go as fast as possible."
