How many kms is the Tour De France?

Answer 1

The Tour distance varies from year to year. In 2007, the Tour was 3570km (2218 miles), while in 2008, it is 3554km (2208). Of course, this is done over multiple "stages", which are really daily races within the three week race.

Answer 2

23 days which includes 2 rest days

The Tour is broken up into 21 stages (town-to-town over a 3-week period), and throughout the years, the standard mileage has been between 1500-2000 miles.

The 2008 Tour de France features 21 stages, which means 21 days of racing. The Tour de France also has 2 rest days, so each edition of the race lasts 23 days in total; always starting on a Saturday, it finishes three weeks later on a Sunday.
The Tour de France is 3500 km (2175 miles), divided into 21 stages over a period of 23 days (with 2 rest days).

The Tour de France covers around 3500 kilometers during its three-week duration.

It varies slightly from year to year, but not much. It is made up of different stages so it is never exactly the same. It averages about 3500km. For example, in 2007 it was 3570km and in 2008 it was 3554km.
2,230 miles approx
3600 KM, 2235 miles.
More than 6,100 kilometers or 2,235 miles.
It varies every year, but the 2011 Tour de France was 3,430.5 kilometers (2,132 miles) in length.

The Tour de France 2012 was 3,497 kilometres long (2,173 mi).

This year (2011), the Tour de France covered a total distance of 3,420.5 km.
One year's winner, Cadel Evans, reached the finish line in Champs-Élysées after 86 hours, 12 minutes and 22 seconds on the bicycle.

The race is 21 stages, one per day, with two rest days, equalling a total of 23 days. The miles/km change each year depending on the route that's taken.
