GNCC Racing



Transponder scoring is the official timing and scoring system for GNCC. We use Sport-Tag brand RFID transponders.

You must have a transponder BEFORE you register at the event.

If you are pre-entered, you must first get in line to pick up your helmet tags, class color and any other items from GNCC in the pre-entry line, then the attendant will pass your envelope to the transponder line where you will head next to get your transponder. After they have written the transponder number on your envelope you are good to go. Your registration is complete.

Transponders can be purchased or rented. The purchase price/rental deposit is $100 - CASH or CREDIT; if using credit, there is a convenience fee.

You are responsible for having a current transponder. Check your transponder expiration date to ensure it’s still good. The last thing you need is for your transponder to expire during a race. You worked hard for those laps and you don’t want to lose them over a bad transponder! 

Purchase: Newly purchased transponders are good for two to three years after activation and expire on the date stated on the front of the unit – not from the date you bought it. Please make a note of the expiration date upon purchase. Expired units cannot be used, and you will need to buy a new one.

Rental: The rental fee is $15.GNCC Racing will hold a $100 deposit, and you will receive a $85 when you return the transponder at the end of your race. If you fail to return it that day, we will charge your credit card $100 and you can keep the transponder.

When you rent, we will give you a receipt to verify your deposit and your transponder number. Please return the receipt along with the transponder after your race. Things go much faster if you have the receipt and if you paid by cash! If you secured the transponder by credit card, your card will be charged $15. If you would like to pay the $15 rental fee in cash, just tell the transponder attendant.

You must return the transponder in the same condition it was in when you rented it. If it's broken, just plan on keeping it.

If you have forgotten to return your transponder at the event, please email [email protected] for instructions on how to return. 


Please don't carry your transponder with you to the Finish Line area. Some riders stop by the Finish Line to watch the racing action, not realizing that the transponder in their pocket will be picked up by the scoring system. This causes a lot of unnecessary confusion with "phantom" hits and drives the scoring team nuts! So just be careful.
