Move for BIG!

20km of Brussels, 19 May 2019 at 10.00 

Now is your chance to run, walk, or cheer for BIG!

It’s our 20th anniversary and to mark the occasion we are inviting our supporters to join us on race day.

Each km marks one year since BIG has been committed to finding better treatments against breast cancer.

BIG has made achievements in the field. Your participation brings us one step closer to finding the cures.


Participation fee €25. Once you sign up to run for BIG you will be invited to create a personal fundraising page, so your friends and family can support the cause close to your heart – advancing breast cancer research.

Donations over €40 are tax deductible for Belgian residents. 

Visit BIG's HQ before race day to collect your bib-number or meet us at Delen Bank near the start and finish line to collect your number on May 19. When you run with us you can skip the line-ups and receive a free t-shirt to run in. 

Reminder to register before 2 May. Don't delay, spots are limited!

For all questions, please contact philanthropy [at]

See you on 19 May!
