29.11.25 — Brussels Boulder Battle (BBB) at Petite Île!

From 16h to 20h, we’re hosting the first round of the Brussels Boulder Battle (BBB)! To learn more about the competition, check the link in bio or look at our previous posts for all the details.

There will be 3 prizes for women and 3 prizes for men!
To participate, simply sign up on the BBB website — it’s free and there’s no obligation to join other sessions. (Link in bio) You can also register on-site with the help of our crew.

In total, 30 bouldering routes will be set up for the event, along with the usual routes on the gym’s walls.
To avoid congestion, the competition routes will be spread across all walls.

Important note: As you know, Petite Île prefers liquid chalk over powder, as it keeps the air clearer. We highly encourage you to bring liquid chalk, but if you use powder, please keep it in the designated buckets and limit its spread.

We can’t wait to see you there, motivated and ready to give it your all!
Keep your t-shirt on and leave your ego at the door – just focus on having fun!
