CHRONOTRACK TIMING SYSTEM
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.
