Miguel Indurain

Miguel Indurain achieved five consecutive Tour de France titles from 1991 to 1995, becoming the only rider to secure this five-peat until the modern era. His 7 grand tour wins include two Giro d'Italia victories alongside his Tour dominance. This streak surpasses Jacques Anquetil's five wins by being consecutive, a four-year span of supremacy that outpaced the typical career arcs of rivals like Hinault. Indurain's largest Grand Tour margin of victory was 4 minutes 35 seconds, reflecting a 25% higher average lead than other multiple winners.
