The transponders may be kept for as long as you decide to race.
The transponders used by the Race Timer system are EXTREMELY durable, requiring virtually zero maintenance. When ready to use, they’ll be programmed with your rider number, and as you change classes / rider number through the years, you need only reprogram it with your new rider number.
The system is easily able to differentiate between riders at the checkpoint – regardless how close they are together. If you have lost of forgotten your transponder, additional transponders are available at signup.
The transponder must be affixed to the inside of your helmet visor. The transponder will not work if it is mounted anywhere else. Take the time to ensure that the transponder is securely mounted. Remember – the transponder is YOURS, so take the extra time to ensure you don’t lose it.
