Final answer:
The Tour de France, marked by the awarding of the Maillot Jaune, is a 23-day cycling race. Lance Armstrong, despite his stripped titles, is one of its most famous competitors. The race encompasses various terrains, including challenging hill climbs.
Step-by-step explanation:
The 23-day race that ends each day with the awarding of the Maillot Jaune is known as the Tour de France. This race is one of the most prestigious cycling events in the world, and the Maillot Jaune, which is French for 'Yellow Jersey', is awarded to the cyclist with the lowest overall time at the end of each stage. The wearer of the Maillot Jaune often changes throughout the race as different riders gain or lose time on their competitors.
One renowned cyclist who has participated in the Tour de France was Lance Armstrong. He famously won the race seven consecutive times from 1999 to 2005, although his titles were later stripped due to doping violations. The Tour de France is not just about the flat roads--it includes stages with varied terrain, such as the steep hills mentioned in the student's question. Climbing these hills is a critical aspect of the race strategy, and the vertical height of a hill, such as the 70 meters mentioned, can have a significant impact on a cyclist's performance.
