The Tour of Flanders (Dutch: Ronde van Vlaanderen), also known as De Ronde ("The Tour"), is an annual road cycling race held in Belgium every spring. The most important cycling race in Flanders, it is part of the UCI World Tour and organized by Flanders Classics. Its nickname is Vlaanderens Mooiste (Dutch for "Flanders' Finest"). First held in 1913, the Tour of Flanders had its 100th edition in 2016. Since 2004, a women's race, the Tour of Flanders for Women, is organized annually on the same day as the men's but on a shorter distance.
