The Gent–Wevelgem U23 / Kattekoers-Ieper is a European single day cycle race held in the Belgian region of Flanders. As of 2011, the race is organized as a 1.2 event on the UCI Europe Tour. The race is considered to be the under-23 version of the Gent–Wevelgem classic.
The Kattekoers was created in 1934, initially as The three belfry cities. The race started in Ghent, passed Bruges and ended in Ypres, three cities which have a belfry, hence the name. More recently, the starting location has been changed to Deinze instead of Ghent.
