The Tour de France is won by the rider who completes the 21-stage race in the fastest total time.

Each stage is timed from start to finish and the times are added together for each rider as the tour progresses. The rider with the lowest cumulative time across all stages is declared the winner.

The tour consists of flat, hilly and mountain stages, covering a distance of 3,320km (2,063 miles).

The winner earns €500,000 (£433,665) in prize money.

Meanwhile, the Tour de France Femmes for female riders is a nine-stage event starting a day before the end of the Tour de France.

It is raced over 1,168km (725.8 miles) and has a winning prize pool of 50,000 euros (£43,366).
