Frequently Asked Questions
How do I wear a multisport tag?
For multisport events we use an ankle-mounted tag that comes with a velcro strap to secure it. The tag should be fitted onto the strap and then secured around the left ankle. We recommend the left ankle is always used because this eliminates any risk of the strap being caught in the chain of your bicycle – it has nothing to do with timing system performance.
Always wear the tag on the outside of your leg, not inside where it will bang on the pedal crank and annoy you or behind where it will probably rub on your heel.
Always fit the timing strap and tag before putting on a wetsuit – if you put the strap over the wetsuit you effectively tie the suit onto your leg and transition will become a major struggle!
Multisport chips and straps MUST be returned after you finish a race – they are expensive and organisers will typically bill you between €5 and €35 for any lost tags and straps.
What's the difference between gun time and chip time?
Pretty much every mass start event; run, triathlon, swim and more besides, has what is called a ‘gun’ start. That’s the time that the race officially started and is often signalled by a gun or hooter. Your ‘gun time’ for an event is the difference in time between this time and the time that you finished. This is the time that will be used to calculate your overall position or ranking.
An event with a gun start may have many waves, triathlon being a typical example, and in this case each wave will have its own gun start time.
When an event provides a start line timing point, and many running races do, you’ll also get a time recorded when you go across the mat. You may cross the mat some seconds (or even minutes!) after the official start. Your ‘chip’ or ‘net’ time is the difference in time between this time and the time that you finished. This is your personal ‘point to point’ time for the race, it is not generally used to calculate positions, etc. Use it for bragging rights about your PBs but remember, it’s the first person over the line who wins in a running race!
Some races have individual starting times; typically cycle time trials and sportives and some multisport races where you start either individually in a pool or in very small groups. Here there is no actual ‘gun’ time and so only the ‘chip’ time gets used.
Results will be texted to participants after the race and a link will be also texted and emailed to all participants failing that visit www.coretiming.com/results All the events timed under the Race Timing System are still online and available long after the race- just type the event name into the search box on the main page and you’ll find them. In almost all cases, results are available to race organisers in real-time as they are constantly being downloaded to our timing computers and processed in real-time. Therefore, we can normally provide you with awards reports and top finisher print outs whilst your race is still taking place.
Are Race Bibs Included
Yes, we quote to include our generic race number in the price of the disposable tags. If you wish to have a custom race number then this will cost you more.
What is the Difference between Passive RFID and Active RFID?
Generically, there are two types of transponder timing systems; active and passive. An active transponder consists of a battery-powered transceiver, connected to the athlete, that emits its unique code when it is interrogated. A passive transponder does not contain a power source inside the transponder. Instead, the transponder captures electromagnetic energy produced by a near-by exciter and utilizes that energy to emit its unique code.
In both systems, an antenna is placed at the start, finish, and in some cases, intermediate time points and is connected to a decoder. This decoder identifies the unique transponder code and calculates the exact time when the transponder passes a timing point. Active RFID transponder is equipped with a battery that is used to power its circuitry and antenna. The internal circuitry of the transponder is only activated when it comes near a detection loop, saving battery power and allowing the battery to last for 5 years or about 100,000 passings. Powering each transponder ensures that its unique ID is transmitted to the detection loop for detection, enabling 100% capture of passings.Making its readability very good up to 90cm off the ground.
Passive RFID The RFID timing transponders harvest a tiny amount of electricty from the magnetic field generated by the timing boxes so the signal it uses to broadcast its unique ID is small. In good conditions, RFID transponders will be read anywhere from knee height downwards ensuring higher accuracy.
