Time registration

The timing for all races will take place through the B-Tag. In contrast to previous registration systems, the B-tag must remain attached to the bib number. This will result in less handling of the tag, thereby reducing the chance of errors occurring.

Because the B-tag is attached to your bib number, you can't forget it. The B-tag is also reliable and has been successfully used in various events at home and abroad. Renowned marathons such as the New York Marathon, Chicago Half Marathon and Los Angeles Marathon have already moved to this time registration system.

Running with a B-tag at the ABN AMRO Rotterdam Marathon means:

• That you will be included in the results;
• That you can easily look up your finishfoto;
• That you can see a personalised video

What should I be aware of when securing my bib number to my shirt?

• Your bib number must be worn so that it is clearly visible on your chest
• Your bib number must not be folded or wrinkled
• All four corners of your bib number must be fastened to your shirt
• You can not wear any clothing over your bib number

What is the official time?

The gross time is the official time! It starts when the starting shot is fired and stops when you cross the finish line. The net time is the time when you step on the mat at the starting line and stops when you pass the finish line. This net time is listed as an extra service.
