US Olympic champion Katie Ledecky dismisses suggestions of doping
• 15-year-old obliterates rivals in 800m freestyle final
• Victory provokes comparisons with China's Ye Shiwen

Katie Ledecky has hit back at suggestions of doping after her stunning win in the 800m freestyle final on Friday night.
After blitzing Rebecca Adlington, Britain's best hope for a swimming gold medal, the 15-year-old US swimmer climbed out of the pool and walked straight into a storm, similar to the one that greeted China's Ye Shiwen earlier this week.
Within moments of her win, Ledecky's Wikipedia entry had been vandalised and at her post-race conference, the inevitable inquisition began.
"It's totally false," she replied when asked if she had doped. "I just put in a lot of hard work, this last year and that's all that it's been. It's that simple."
Ledecky was not expected to win gold, but it was the way she won that set tongues wagging as soon as she touched the wall.
In her first international meet, she destroyed the world's best long-distance swimmers, including Adlington, the defending Olympic champion.
Never in danger of losing, she was half a second away from breaking Adlington's world record after charging ahead from the start, but even that was not the root of most of the surprise.
Swimmers spend years trying to shave fractions of seconds off their personal best, but Ledecky has been hacking off large chunks, more than 11 seconds this month.
At the US Olympic trials earlier this month, Ledecky took more than five seconds off her PB to make the team for London. She reduced it by more than another five seconds on Friday to win the Olympic gold.
"I've just progressively set short term goals and long term goals," she said. "I just have been dropping time progressively and just going to some big meets and having some good races and I've been able to get down to where I am here."
Earlier this week, an American coach, not involved with the team or US Swimming, accused China's Ye Shiwen of doping when she won the 400m individual medley gold medal. Josh Leonard said her rapid improvement, which was less dramatic than Ledecky's, was a sign she cheated.
Ye denied any wrongdoing and swimming's world governing body backed her, saying she passed all her drug tests. The Chinese said their accusers were racist and would never point the finger at their own.
