The Big Bertha 2026

Looking for a race that smells like nature and castles, without taking yourself too seriously but still genuinely treating yourself? The Big Bertha in Ans, in the province of Liège, is exactly that: paths that beat the sidewalks, endless green corners, and that little taste of adventure just a stone’s throw from the city 🏰.

You’ve got options: an accessible 10 km (with an non-timed option if you just want to enjoy), or a 16 km to push yourself a bit more—without burning your wings 🔥.

The common thread is simple: you move forward, you breathe, you savor the “postcard” sections, and you let Bertha remind you that you can bring the heat while keeping a smile 😉.

And after the effort, keep the trip going: head to Liège for a city stroll, climb the steps of the Montagne de Bueren (promise, it’s shorter than a climb in the middle of the race), or grab a seat on a terrace around Place du Marché to rehash it all 🍻.

Craving some peace and quiet? Take a detour to the Seraing Estate and its castle, or head as far as Sart-Tilman for a green walk in active-recovery mode 🌿.

Solo, as a couple, or with your crew, you’ll head home with happy calves and a head full of memories: in Ans, you come to run… and you stay to explore! 🗺️
