ChronoTrack Tag

Quick Links


The Amica Insurance Seattle Marathon is timed using the ChronoTrack timing system. A B-Tag timing device is incorporated into your race bib.

In order to receive an accurate time, please confirm that throughout the race your bib is:

  • Clearly visible on the front of the torso
  • Unaltered and unmodified — Do not fold or wrinkle
  • Pinned in all four corners
  • Not covered by jackets, runne belts, water bottles, etc.


The B-Tag is disposable — no need to return your tag after the race.
