20KM of Brussels 2026

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

Join us and enjoy the following benefits:

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

We take care of all administrative procedures related to registration. The 50,000 available race entries usually sell out extremely fast!

Last year, nearly 250 participants joined us!

Thanks to be.Source:

your registration is handled stress-free,

you will receive the official race bib,

as well as a be.Source T-shirt.

You will have access to facilities (changing rooms and toilets) 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!
