Half Marathon Des Boucles Ardennaises

This 21km route highlights the Boucles Ardennaises half-marathon , of which we are a partner for the 2026 edition . In the heart of La Roche-en-Ardenne , the route crosses the Ourthe valley, the surrounding woods, streams and the heights of the Haussire.

The route alternates between a flatter initial section, a long, gradual climb into the hills, and more undulating forest sections before a final descent into the valley. A demanding route, designed for runners seeking a real challenge in the Ardennes.

The route begins in La Roche-en-Ardenne , in an iconic setting dominated by the castle and the Ourthe valley.

The first few kilometers run alongside the Ourthe on a relatively flat section, ideal for gradually getting into the race before tackling the first difficulties.

• La Roche-en-Ardenne : Starting and finishing town, known for its castle overlooking the valley.

• The Ourthe : River followed at the beginning of the route, in the heart of the natural setting of La Roche.
