Chambers looking for world redemption

Dwain Chambers, the "walking junkie" as he termed himself when he was taking performance enhancing drugs, will be looking for a different high at the World Championships where he is out to spoil the Tyson Gay/Usain Bolt 100 metres duel.

The 31-year-old British sprinter has sought unsuccessfully to convince the major athletics meeting organisers to accept him back in the fold after serving a two year ban for doping but should he win a medal here it would make a strong case for him being invited.

Unable to compete at the Olympics, despite going to court over it, it will be the first time he pits his wits at championship level against Gay and world record holder Bolt.

However, Chambers appears to be undaunted at the prospect of taking the great Jamaican showman - who he trained with in 2006 - as he told The Times earlier this year.
