Created in 1923, 24 Hours of Le Mans, is the most famous endurance race in the world. The race teams have to balance speed against the cars' ability to run for 24 hours without sustaining mechanical damage to the car and manage the cars' consumables - primarily fuel, tyres and braking materials. The endurance of the drivers is also tested as drivers frequently spend stints of over two hours behind the wheel before stopping in the pits and allowing a relief driver to take over the driving duties. Drivers then grab what food and rest they can before returning to drive another stint. Today it is mandated that three drivers share each competing vehicle. The race conveys values of sportsmanship, challenge and technologies which men, car manufacturers and the major makes seek to make their own, whether by taking part in the race, standing out through their achievements, or by becoming partners.
