Take part in the 20 km of Brussels and support vulnerable seniors

You will not only push your own limits, but also support seniors facing precarious living conditions or social isolation.

We support you throughout all administrative steps related to the registration process, making it as simple as possible — a real advantage when you know that the 50,000 available spots usually sell out extremely fast!

Last year, we had nearly 250 participants !

With be.Source:

your registration process is made as smooth as possible,

we take care of collecting your race bib,

and you will receive a be.Source T-shirt.

You will have access to facilities close to the start and finish areas.

To ensure optimal race conditions, refreshments will be provided during the event.

After the race, let’s meet up for a drink and a snack — a unique opportunity to share your experience with fellow participants.

And… more surprises are waiting for you! 😉

Beyond the sporting challenge, the 20 km of Brussels is more than ever a celebration of solidarity. We look forward to welcoming you, wearing the be.Source colors, to flood our capital with an incredible wave of sporting and charitable energy!
