ChronoTrack Live has always restricted bibs and tags from being assigned twice within the same Race, but did not restrict bibs from being duplicated between Races in a single Event. Events where duplicate bib assignment is necessary (such as challenge races) still need to retain this ability. For Events where bibs should not be duplicated between races, duplicate assignment could lead to scoring and results headaches later on. We do provide a “Shared Tag in Event” Data Check, but this is only helpful in identifying mistakes after assignment has been given.
We’ve now released a small change to the On-Site Options tab in CT Live that will eliminate mistaken duplicate bib/tag assignment. The Unique Bib toggle will prevent any bib/tag from being assigned to more than one athlete in the entire event.
