In order to guarantee an optimal experience for all participants, the organization has decided to close registration as soon as a certain quota is reached.

The number of bibs for teams is limited to 65% of the total number and they will be allocated on a "first come, first served" basis. 

We will register your entries with the Brussels 20km race organization as soon as you send it. We must receive your registration by Monday 2 March at the latest.
