David Millar says the future's bright for cyclists entering the professional ranks, believing the days of doping are now behind the sport.

The former British road race champion leaves the professional cycling after a 17-year career. Millar wore all three main jerseys at the Tour de France - and won three individual stages, and one team time-trial - and held the leaders jerseys in both the Giro D'Italia and Vuelta a España.

Millar also served a two year ban after admitting taking performance enhancing drugs, before being a vocal anti-doping campaigner on his return. Millar told 91Èȱ¬ Radio 5 live he didn't realise how dark the sport was when he first started.

"I don't think any of us did until we were in it," he said. "But since then it's night and day: then it was night, and now it's day."

"Kids coming in now can have a great, clean career, which wasn't necessarily the case when I turned pro," he added.

Millar, who retired following the Bec CC hill climb event earlier this month, says he's looking forward to his post-professional life, although he's worried about the cost of buying a bike.
