Bib number

A bib number is a unique identifier worn by participants in races, typically pinned to their clothing. It helps organizers track runners' times and positions, and assists in identifying athletes in photos or emergencies. Bib numbers often include timing chips for accurate race timing. In events like marathons, they are crucial for logistical management and ensuring fair competition. For runners, bib numbers are a badge of participation and achievement, often kept as mementos. They also facilitate the distribution of race results and can be used to access race photos and other event-related services.
