What does the last cyclist in the tour the France receive?

Answer 1

the last cyclist used to receive 'la cuillère de bois' (a wooden spoon), which was a valueless trophy but used to bring some fame to the cyclist. It is out of fashion nowadays.
There is no official prize or monetary reward. The last-place rider simply gets the prestige of being known as the "lanterne rouge" or "red lantern," signifying the red lights at the tail or caboose of a train.
The last rider in the Tour de France is historically referred to as the "Lanterne Rouge" (meaning: Red Lantern). This is a reference to the older trains which hung a red lantern off the last car to signify the end of the train.
