John James 'Sean' Kelly is an Irish former professional road bicycle racer, one of the most successful road cyclists of the 1980s, and one of the finest Classics riders of all time. From becoming a professional in 1977 until his retirement in 1994, he won 193 professional races, including nine Monument Classics, Paris–Nice a record seven years consecutively and the first UCI Road World Cup in 1989. Kelly won one Grand Tour, the 1988 Vuelta a España, and four green jerseys in the Tour de France. He achieved multiple victories in the Giro di Lombardia, Milan–San Remo, Paris–Roubaix and Liège–Bastogne–Liège, as well as three runners-up placings in the only Monument he failed to win, the Tour of Flanders. Other victories include the Grand Prix des Nations and stage races, the Critérium International, Tour de Suisse, Tour of the Basque Country and Volta a Catalunya.

The Monuments are five classic cycle races generally considered to be the oldest, hardest, longest and most prestigious one-day events in men's road cycling, with distances between 240 and 300 km.
