Background: Miguel Indurain Larraya (Spanish pronunciation: [mi'gel indu'rain la'raja]; born 16 July 1964) is a retired Spanish road racing cyclist. Indurain won five consecutive Tours de France from 1991 to 1995, the fourth, and last, to win five times.
Context: He also won the Criterium du Dauphine Libere in 1996.  Indurain aimed for a sixth victory in the 1996 Tour, but suffered from the beginning. He came seventh in the prologue. After bronchitis in a cold and wet first week, he lost time from stage seven. He said that, on the Cormet de Roseland on 6 July, "my legs started to feel odd but, because the speed of the group wasn't very high, I didn't take much notice. I even imagined attacking at the foot of the Arcs climbs." He dropped out of the group and lost three minutes in three kilometres. Race referees penalised him 20 seconds for accepting a bottle of drink in the last kilometre. He said the 20 seconds were nothing compared to the minute he would have lost had he not taken the bottle. He later said he would stop racing. The Dane Bjarne Riis won and his teammate Jan Ullrich finished second. Indurain finished 11th and, in a stage passing through his hometown and ending in Pamplona, he finished 19th, eight minutes behind the stage winner.  He won the individual time trial in the 1996 Olympic Games in Atlanta, where professionals competed for the first time.  In September 1996 Indurain rode the Vuelta a Espana at the insistence of his team. He dropped out unexpectedly on the Mirador del Fito, 30 km (19 mi) from the end of the stage to Covadonga. Relations with his team manager, Jose-Miguel Echavarri, had been difficult since an aborted attempt on the hour record in Colombia in October 1995. The two no longer speak.
