Regardless of what some believe, this is the biggest and brashest bike race in the world, with an estimated 80 per cent of most WorldTour team's sponsorship income being based around the Tour.
Founded in 1903 by Henri Desgrange, editor of L'Auto newspaper, the Tour may not be the favourite stage race of the cycling cognoscenti but it is one that captures the imagination of the wider sporting public. As a result, the race is the biggest annual sporting event in the world with more live spectators than even the Olympics or football World Cup.
The second grand tour of the season comprises 21 stages and will be contested over 3,328 kilometres – that's 2,068 miles in old money – which is an average of 158.47km (98.46 miles) per day.
And when does the Tour de France finish?
The Tour de France concludes with its traditional final stage in Paris, on Sunday July 21. The race will again end on the famous cobbled Champs-Élysées boulevard following a 115.6km saunter from Paris La Défense Arena on the outskirts of the city.
