Before starting the Tour, Merckx had spent a large amount of his time resting and training, racing only five times. Merckx won the race's sixth stage through attacking before the leg's final major climb, the Ballon d'Alsace, and then outlasting his competitors who were able to follow him initially. During the seventeenth stage, Merckx was riding at the head of the race with several general classification contenders on the Col du Tourmalet. Merckx shifted into a large gear, attacked, and went on to cross the summit with a 45-second advantage. Despite orders to wait for the chasing riders, Merckx increased his efforts. He rode over the Col du Soulor and Col d'Aubisque, increasing the gap to eight minutes. With close to fifty kilometers to go, Merckx began to suffer hypoglycemia and rode the rest of the stage in severe pain. At the end of the stage, Merckx told the journalists I hope I have done enough now for you to consider me a worthy winner. Merckx finished the race with six stage victories to his credit, along with the general, points, mountains, and combination classifications, and the award for most aggressive rider.
