Alan Oliveira Berlin June 15 2013June 15 - Brazil's Alan Oliveira has become the fastest leg amputee sprinter on the planet, obliterating the 100 metres world record with a time of 10.77sec at the International Paralympic Committee (IPC) Athletics Grand Prix in Berlin.

The 20-year-old from Marabá, the London 2012 T44 200m gold medallist, led from start to finish to smash the previous T43 world best time, jointly held by Oscar Pistorius and Blake Leeper, by 0.14.

The time also beat the T44 100m world record, held by Britain's Jonnie Peacock at 10.85 and unofficially equalled by his American rival Richard Browne last week in Monteverde.

The sprinters, who won gold and silver respectively at London 2012, have been embroiled in a slanging match this week, but the two-horse-race they appeared to have anticipated has been gatecrashed by Oliveira, who will surely now go into the World Championships in Lyon next month among the favourites to take gold in the T44 100m and 200m events.

The Brazilian won bronze two years ago in Christchurch in the 100m in a time of 11.43, behind Oscar Pistorius and Jerome Singleton, who took silver and gold respectively, both clocking 11.34.

Peacock reacted to hearing the news of Oliveira's world record via Twitter, saying: "gonna be a fun year :)".

The 2013 IPC World Championships will be the biggest gathering of Paralympic athletes since London 2012, with around 1,300 athletes from 90 nations expected to compete in Lyon from July 19 until 28.
