The Kemmelberg Trail is a September trail run held in Kemmel, Heuvelland, West Flanders. It provides four distances—7, 10, 20, and 29 km—allowing participants to select a short hill-country outing or a longer route with multiple ascents. While categorized as a city trail, the course is predominantly rural and hilly.
Each distance crosses the Kemmelberg, a 156-metre hill and Flanders' highest point outside the Voerstreek. The longer routes also include the Lettenberg, Baneberg, Rodeberg, and Monteberg, utilizing forest paths and the steep hills rising from the Flemish countryside. The region has Great War history, and the higher elevations offer clear views across the landscape; it is also recognized by many Belgians from the TV series Eigen Kweek.
