Sprinter Asuka Cambridge has set his sights on a place in the 100-meter final at his IAAF World Athletics Championships debut next week, but he knows he must learn from past mistakes if he is to make his mark.

Speaking to reporters at Haneda airport before taking off for the Aug. 4-13 championships in London, the 24-year-old admitted the prospect of running in the long-awaited-for event is playing on his emotions.

"I've always been excited (about competing in the worlds). I can feel my heart racing," Cambridge said.
