In Rome, in 1960, when 'Flying Sikh' Milkha Singh produced a     dream run in the final of the men's 400m. Again in 1984, in Los Angeles, when 'Payyoli Express' P T Usha, in the 400m hurdles, was within a heartbeat of winning bronze, glanced back over her shoulder, and lost it.     Was it a triumph, for those two athletes to have performed as     well as they did? Or heartbreak, to have let glory slip by     milliseconds? See the videos of their runs, and decide for yourself.
