Pneumonia forced him to quit racing for a month and forced him to enter the Giro d'Italia in poor form. He lost time early in the race to Fuente, who took the race's first mountainous stage. Merckx gained time on Fuente in the race's only time trial. Merckx attacked from two hundred kilometers out two days later in a stage that was plagued by horrendous weather. Fuente lost ten minutes to Merckx, who became the race leader. The twentieth stage had a summit finish to Tre Cime di Lavaredo. Fuente and Gianbattista Baronchelli attacked on the climb, while Merckx was unable to match their accelerations. He finished the stage only to see his lead shrink to twelve seconds over Baronchelli. He held on to that lead until the race's conclusion, winning his fifth Giro d'Italia. Three days following his victory at the Giro, Merckx started the Tour de Suisse. He won the race's prologue and rode conservatively for the rest of the race. He took the final leg, an individual time trial, to seal his overall victory. After finishing the race, Merckx had a sebaceous cyst removed on 22 June. Five days following the surgery, he was scheduled to begin the Tour de France. The wound was still slightly open when he began the Grand Tour and it bled throughout the race. At the Tour, Merckx won the race's prologue, giving him the first race leader's "maillot jaune" (), which he lost the next day to teammate Joseph Bruyère. He won the seventh stage of the race, and regained the lead, through attacking in the closing kilometers and holding off the chasing peloton. He put five minutes into Poulidor, his main rival, after dropping him on the Col du Galibier. The next day, on the slopes of Mont Ventoux, Merckx rode to limit his losses after suffering several attacks from other general classification riders, including Poulidor, Vicente López Carril and Gonzalo Aja. He expanded his lead through several stage victories afterward, including one where he attacked with ten kilometers to go in a flat stage and held off the peloton to reach the finish in Orléans almost a minute and a half before the chasing group. Merckx finished the Tour with eight stage wins and his fifth Tour de France victory, equaling the record of Anquetil.
