What is a BIB number?

A BIB number is the bib number assigned by the organization to each participant. It appears on two items provided before the start:

• a bib to attach to the front
• a bib to attach to the back (often on the backpack)

These bibs measure approximately 18 cm x 16 cm, carry the same unique number, and are used for identification, control, and timing throughout the event.
