In true Grelly tradition, every edition brings brand-new tracks through lesser-known corners of Belgium and beyond. After exploring the western Sauerland from Eupen last year, we’re heading in a new direction for 2027: west and south, with France as the only country outside Belgium. Start and finish are in Herbeumont, a tiny village on the Semois.

Metz and Nancy may remind you of a dull stretch of motorway on the way south, but several recce rides proved us wrong. Lorraine is our playground for ‘27. The longest route passes Nancy and Toul, south of the Moselle. The shorter routes cross the Lorraine Regional Nature Park, and every route visits Verdun, where World War I remains appear along the way.

There’s less climbing than in previous editions, so the kilometres should roll a bit easier. Resupply and overnight options are scarce, though, so come prepared! For the bold, there’s also a small XXL loop along the meandering Semois, west of Herbeumont.

Choose 3 or 4 days of adventure on one of our 4–5 routes from Herbeumont (BE), ranging from 350 to 825 km. Maximum unpaved fun: not too technical, never dull!
