Mark Cavendish is Britain's most successful Tour de France cyclist.
At the time of writing, Cavendish is the World Road Race champion, holder of the green jersey from the 2011 Tour de France, and Sports Personality of the Year. And he is a long way from being finished yet.
Outrageously talented and often controversial, specialist sprinter Cavendish has amassed 20 stage wins in the past four Tours. The 2011 race brought him the green jersey for the first time in his career after several attempts, and his third straight stage victory on the famous Champs-Elysees in Paris.
For the 2012 season he has joined British-based Team Sky to race alongside compatriot Bradley Wiggins. Wiggins is the favourite for the overall race and will be the team leader, but there will be days when 'Cav' comes to the fore and aims for stage victory.
Team Sky's tactics will be fascinating to see. Can they challenge for the yellow jersey and the green jersey in the same race?
Born and raised on the Isle of Man, Cavendish's fiercely competitive spirit has also brought him two World Championship titles on the track, a Commonwealth Games gold medal, and victory in the spring classic Milan-San Remo in 2009.
Cavendish will ride this year's Tour in the rainbow colours of world champion. His dramatic sprint victory in Copenhagen with an eight-strong team will doubtless remain one of the high points of his career, following in the footsteps of British cycling legend Tom Simpson, Britain's last world champion.
As if that wasn't enough, Cavendish has also claimed 10 stages in the Giro d'Italia and worn the pink race leader's jersey. He also took the points classification at the Vuelta a Espana in 2010.
There is simply no-one faster than Cav in a sprint.
Why will he never win the Tour? Because he's a sprint specialist who will never thrive in the mountains stages or in time trials. To win the Tour de France, all-round ability is crucial, and Cavendish excels in one element of bike racing: sprinting.
In 2009 he was controversially punished for blocking sprint rival Thor Hushovd as they raced for the line on Stage 14 in Besancon. Consequently he lost ground in the battle for the green jersey which Hushovd eventually won.
Cavendish again finished second, this time to fellow sprinter Alessandro Petacchi, in the points standings in 2010. He achieved his goal in 2011, and went on to win the World Championships in Copenhagen two months later.
This year Cavendish will be going for gold in London in the Olympic Road Race just six days after the end of the Tour. It is an incredibly demanding schedule, both mentally and physically, but as Cavendish says all his main rivals in the Olympic Race will also be riding in the Tour.
There has been speculation that Cavendish may choose not to ride all the way to Paris in 2012, saving his energy for the Olympics, but he insists this is not the case.
Cavendish has become a father in 2012, something he insists has provided him with even more motivation to succeed as a cyclist. His rivals should be very concerned about that.
