At this moment it has not yet been determined when registration for the TCS Amterdam Marathon 2021 will start. As soon as we have an update about this, we will announce this on our website.
Were you registered for the 2020 edition? Your bib number including ordered extras will remain valid for the 2021 edition. Before the registration opens, we will inform you by e-mail how you can transfer your old bib number to the 2021 edition.
