Indian athletes continued to cut a sorry figure on the Olympic stage and Mandeep Kaur could not lift the gloom as she failed to qualify for the semi-finals of the women's 400m event here today.Mandeep timed 52.88 to finish sixth in the seven-athlete Heat Two and 33rd overall. The first three from each of the seven heats and the next three fastest made it to the semi-finals of the event.Long shotVikas Gowda's campaign wilted in the qualifying round itself with the US-based Indian discus thrower failing to reach anywhere near his personal best here today.Gowda hurled the discus 60.69 to finish 11th in Group A and 22nd overall. His performance on Saturday was way below his personal best and national record of 64.96m, which he achieved in May last year in Salinas.Gowda, who comes from the same University of North Carolina that produced basketball legend Michael Jordan, started on a poor note, clearing 59.58 and after a botched attempt, signed off with 60.69 which was far below the qualifying mark, set at 64.50 or the 12 best performers.
