To change a racer’s timing chip or racer number, find the racer by entering their name or their current racer number or timing chip in the search box on the “Racers” page of your race:

Click the racer’s name to access the “Racer Info” screen corresponding to that racer. Then, scroll down to the Racer Number or Timing Chip field, erase the existing value, and enter the new racer number or timing chip to assign to this racer.
If the race has already started
Changing a racer’s timing chip or racer number does not automatically change any of their timing data – if times were assigned to a racer based on an incorrect timing chip, you will need to clear all the racer’s assigned times and re-process the racer after changing the timing chip or racer number.
