Mark Simon Cavendish (born 21 May 1985) is a British professional road racing cyclist from the Isle of Man who rides for UCI WorldTeam . As a track cyclist he specialises in the madison, points race, and scratch race disciplines; as a road racer he is a sprinter. He is widely considered one of the greatest road sprinters of all time, and in 2021 was called "the greatest sprinter in the history of the Tour and of cycling" by Christian Prudhomme, director of the Tour de France. In his first years as an elite track rider, Cavendish won gold in the madison at the 2005 and 2008 UCI Track Cycling World Championships riding for Great Britain, with Rob Hayles and Bradley Wiggins respectively, and in the scratch race at the 2006 Commonwealth Games riding for Isle of Man. After failing to win a medal at the 2008 Summer Olympics he did not compete on track again until 2015, subsequently winning his third UCI Track Cycling World Championships title with Wiggins in the madison in 2016, and an individual silver medal in the omnium at the 2016 Summer Olympics. As a road cyclist, Cavendish turned professional in 2005, and achieved eleven wins in his first professional season. Cavendish has won 34 Tour de France stages, tying him for first on the all-time list with Eddy Merckx, contributing to a third-highest total of fifty-three Grand Tour stage victories. He won the Men's road race at the 2011 road world championships, becoming the second male British rider to do so after Tom Simpson. Cavendish has also won the points classification in all three of the grand tours: the 2010 Vuelta a España, the 2011, and 2021 Tours de France and the 2013 Giro d'Italia. In 2012, he became the first person to win the final Champs-Élysées stage in the Tour de France in four consecutive years. He won seven Grand Tour stages in 2013, one in 2015 and four in 2016. This included a win on stage one of the 2016 Tour de France, claiming him his first Tour de France yellow jersey of his career. Cavendish crashed with Peter Sagan on stage four of the 2017 Tour de France, forcing him out of the race. Cavendish continued producing good results until August 2018, when he was diagnosed with Epstein–Barr virus. Before his diagnosis, Cavendish was able to compete in the 2018 Tour
