Race Bib Number New York City Marathon 2025 – What You Need to Know?
Key Role of the Race Bib in NYC Marathon
Your race bib serves as an identifier, tracking device, and timing instrument. It contains an integrated chip (ChronoTrack B-tag), which measures your time and enables live tracking on course. Careless attachment or incorrect use creates timing errors and the risk of disqualification.
- The bib must be fully visible on the front of your torso throughout the race.
- Do not bend, cut, iron, or deform it (antennas on the back must remain uncovered to enable timing).
- It must be fastened at all four corners to your running apparel, not to a backpack or belt.
- It cannot be covered by layers such as jackets, especially those with zippers or metal parts that interfere with reading.
Bib Structure: Colors, Waves, and Corrals
The NYC Marathon 2025 bib acts as a map of your start. It consists of several key markings:
- Background color (BLUE, ORANGE, PINK) indicates your start village and start line – your assigned gathering area in Fort Wadsworth.
- Wave number (1-5) shows your wave group for race start times.
- Corral letter (A-F) identifies your starting corral within the wave and color group. Letters earlier in the alphabet are closer to the start line.
- The bottom strip contains runner info: name, age, gender, team, assigned bus/ferry transport, and baggage dematerialization option.
Bib Data and Important Notes
Printed in the bottom left corner are your name, age, gender, transport assignment, and team. An indication of the Baggage Pre-Check option also appears (this is a separate baggage drop procedure).
Very important: medical emergency information must be filled out on the back of the bib – this ensures medical personnel have quick access to vital health and contact info in case of an emergency.
Consequences of Improper Bib Use
- Race bibs are NON-TRANSFERABLE; they are assigned to each runner personally. Transferring results in disqualification and suspension from NYRR events.
- Failure to wear a bib properly (hidden, rotated, or missing) may lead to loss of timing or disqualification.
- Failure to abide by bib placement rules also disables live tracking and compromises medical safety.
