The British Olympic Association excludes athletes which have previously served doping bans from competing at Olympic Games. Recently, the World Anti-Doping Agency declared this stance "non-compliant" because the Games ban is viewed as an "additional sanction".

David Millar is one of three British athletes who are affected by the ban, along with sprinter Dwain Chambers and shot-putter and discus thrower Carl Myerscough, but says he won't fight the British Olympic Association ruling.

"In all honesty, I'd written off the Olympics a long time ago," Millar told the BBC.

"I just considered that the lifetime ban was in place and it wasn't something I wanted to challenge," he continued.

"There are certain fights I don't want to fight and that was one of them.

"I just don't fancy being vilified any more. It's been a tough couple of years."

Millar continued by saying that the lifetime ban leaves no room for athlete rehabilitation and that each case needs to be considered on its own merits.

"Imagine you have a 16-year-old who's been given something by their coach and goes positive and receives a lifetime ban, that doesn't seem fair," he suggested.

"But maybe, if you have a 34-year-old multi-millionaire who lives in Monte Carlo, with a team of medical staff, who goes positive, maybe they should get a lifetime ban for a first offence."

What would you have done in his position? Would you fight for your right to race or not?
