When he was four, Marc Marquez asked for a motorbike for Christmas and, with two training wheels, he never looked back. The following year, 1999, his father bought him a second-hand 50cc bike, and in 2000, he was runner up at the Motocross Catalan Championship. A year later, he took another step forward and was Catalan Champion of the initiation category.
He kept competing in motocross but in 2002 he started to focus in road racing, taking part in the Open RACC 50. It was supposed that his first year should be one of adaptation and learning, but Marc won the championship with an overwhelming performance, sometimes finishing some races with an advantage of 20 seconds over his rivals. The following year Marquez jumped to the 125 class with a Honda 125 GP and finished runner-up behind team mate Pol Espargaro.
2004 was an important year for Marquez when he met Emilio Alzamora, 1999 125cc World Champion. During that season Marquez won the 125cc Catalan Championship, as well as the 85cc class of the Supermotard Catalan Championship. The following year he repeated the Catalan triumph, and at the same time made his debut in the Spanish Road Racing Championship (CEV), where he achieved eighth overall position. In 2008 he made his debut in the Motorcycling World Championship with the Repsol KTM Team. Marquez gave glimpses of his talent in his very first race, but it was in his sixth race, at the English Grand Prix, where he was able to set a milestone in motorcycling history. Marquez reached the finish line in third position, the youngest rider ever to get on a World Championship podium and the youngest Spanish rider to achieve that feat. In 2009 at the French Grand Prix, the Repsol rider was the second youngest rider ever to get a pole position in the World Championship.
2010 saw Marquez switch to the Ajo Motorsport team on a Derbi and he was able to show his full potential becoming 125cc World Champion at 17, after getting 10 victories and 12 pole positions. With the title in the bag, the young rider made the move up to Moto2 for 2011. He did so as part of a team created especially for him, boasting experienced mechanics and the same Repsol support that had helped his career in 125cc. Seven wins, three second places and a third place gave Marquez the Rookie of the Year honour for 2011, although his season ended on a sour note when he crashed in qualifying for the penultimate race of the season in Malaysia and was unable to compete in the final two events. That meant that he conceded the title, albeit taking a credable runner-up spot in the Moto2 World Championship.
The start of 2012 was not easy for Marquez, who missed almost the entire preseason whilst recovering from an injury sustained in free practice for the 2011 Malaysian Grand Prix. Marc recovered in time for the Qatar Grand Prix, the first race of 2012, but had accumulated very few miles on his Moto2 bike. The Repsol rider overcame everything thrown his way and and took the 2012 Moto2 World Championship title.
