On the spot – British cyclist David Millar sits down with CNN's Amanda Davies ahead of the 2013 Tour de France.
Fighting from the front – Millar is riding in the 2013 Tour for the Garmin-Sharp team. His career has seen him sink into the depths of doping despair before rising to become a key figure in cycling's battle against drugs cheats.
Into the saddle – The Scot, who was born in Malta in 197, is pictured here competing at the 1997 Road Cycling World Championships. He signed his first professional contract with the Cofidis team.
Youngster in yellow – Millar announced his arrival on the global stage by winning the prologue of the 2000 Tour de France, his first involvement in cycling's most prestigious race.
Arrested and banned – His career was derailed in 2004 when Millar was arrested and detained by French police while having dinner with British Cycling's performance director Dave Brailsford. Millar was subsequently banned from cycling for two years.
Tour return – Millar's ban expired weeks before the start of the 2006 Tour de France, during which he rode for Saunier Duval-Prodir. He finished 59th out of the 139 riders who completed the race.
Golden glory – The Scot represented his country at the 2010 Commonwealth Games in Delhi, India. Millar took gold in the Time Trial event and bronze in the Road Race.
Reprieved – Millar's ban looked to have ended his hopes of competing in the Olympic Games as the British Olympic Association had a policy of issuing lifetime bans to drugs cheats. But the Court of Arbitration for Sport ruled the policy was not compliant with the World Anti-Doping Association's code. The ruling opened the door for Millar, who was part of the British team for the Road Race at the London 2012 Olympic Games.
