Marc Márquez Alentà (born 17 February 1993) is a Spanish Grand Prix motorcycle road racer and one of the most successful motorcycle racers of all time with six Grand Prix world championships to his name - four of which are in the premier MotoGP class. Márquez races for Honda's factory team since his MotoGP debut in 2013. Nicknamed the "Ant of Cervera", he is one of four riders to have won world championship titles in three different categories, after Mike Hailwood, Phil Read and Valentino Rossi.
Márquez won the 2010 125cc World Championship, the 2012 Moto2 World Championship, and the 2013, 2014, 2016 and 2017 MotoGP World Championships. Márquez became the first rider since Kenny Roberts in 1978 to accomplish the premier class title in his first season, and the youngest to win the title overall. In 2014 he defended his title, winning the championship with three rounds to spare, during which he won ten races in a row. He is the older brother of 2014 Moto3 world champion Álex Márquez. Márquez equalled the all-time Grand Prix record for pole positions at the age of 23 in 2016. Márquez secured the 2016 title with three rounds to spare at Motegi, before sealing the title at the final round in 2017.
