Timing Chips
Timing chips will be handed out at registration. You will receive exact instruction from the timing company as to how to affix your timing chip. Do not lose your chip. If you lose your chip, please report to the registration team onsite. Do not trade your chip with another athlete. your chip is linked to your race information.
The chip must be worn during the entire race (swim, bike, run) to produce accurate timing data. It is the athlete’s responsibility to cross each timing mat. All chips
must be returned at the finish line. If you forget to return your chip, you may also hand it at the information tent. Be sure to let the staff know your name and racing
number. If you are unable to complete the race, return your timing chip at the information tent and inform race staff and/or officials.
Relay members: you must hand off the timing chip to your teammate(s) after completing your leg(s) of the race.

At packet pick-up, athletes will be given a wristband that must be worn during the race. This wristband also will allow athletes into transition at bike check-in Sat.,
before the race Saturday morning and also into post-race food. For the safety of the athletes and their gear, no one will be allowed into transition without a wristband. DO NOT REMOVE YOUR WRISTBAND UNTIL THE COMPLETION OF YOUR RACE.
