CORE Manual - Fast Start Guide for Sports
Before using the CORE sensor for sports, first complete CORE sensor setup and ensure you have the latest CORE app and that your sports devices are also up-to-date.
1. Pair your Heart Rate Monitor (HRM)
For sports, CORE provides more accurate metrics when paired to your ANT+ Heart Rate Monitor.
The HRM only needs to be paired once (and CORE will find the HRM automatically). Pairing is easy using the CORE iOS App or CORE Android App.
To check that the heart rate monitor is paired the app will show the 'heart rate icon', your beats per minute and sports mode. Alternatively, shake the CORE, following the initial green flashed that the battery power, a single fast flash indicates no heart rate monitor is connected and a double fast flash confirms the hear rate monitor is connected.
2. Connect to your bike computer or sports watch for real-time data and recording
Once paired and the data fields are setup, most sports devices automatically find and connect to the CORE sensor and record the core body temperature into the FIT file.

3. Wearing the CORE correctly
It is recommended to wear the CORE sensor 10 minutes before starting an activity so that it will provide accurate readings when you begin your activity.
For the best results, the CORE sensor is positioned on the side of the torso (apical). For cycling and triathlon, clipping to the heart rate monitor strap is the most convenient solution and for running, the medical-grade sports adhesive patches can be used. The CORE sensor can also be clipped to a sports bra.
It is personal preference if you choose to position the CORE sensor towards the back or the front of your body, though is recommended to always have the same position each time you wear it.
When clipping to a heart rate monitor strap or sports bra, use the fastening clips to prevent the CORE sensor from slipping off.
Though the CORE can also be worn on an arm-strap, the core body temperature measurements will not be as accurate so it is encouraged to wear the CORE sensor on the torso for sports activities.
4. CORE sensor Battery Life
CORE has a battery life of 5-6 days on one charge. If the sleep-mode is set (via the CORE App), the battery life can be extended up to 1 month (depending on the amount of use) but don't forget to shake the core to wake it up. A single charge takes 2 hours. Read more about charging and battery life.
5. Analysis and actionable data - Understanding core body temperature metrics
Core body temperature is individual and temperature behaviour and responses can be significantly different between people.
We have published extensive information on this website to understand how to training and race with core body data:
Introduction: How to use core body temperature for training and racing
Detailed training information: Heat Training information and the Heat Ramp Test.
The core body temperature and skin temperature metrics recorded in FIT files can be viewed in popular training applications such as Todays Plan, TrainingPeaks, Intervals.icu and more. View the compatibility and setup guides.
The CORE App also synchronises with the CORE sensor and can provide advanced insights including real-time Heat Strain Index, the accumulated Heat Strain Score, Heat Load and core body temperature trends.
Hot Tips
• Take care with the magnetic charging cable - don't leave it plugged in when not in use... to avoid a short-circuit.
• The CORE sensor is not fully validated for Sauna or ice-swimming.
• For heat training, more is not better. Identify your ideal heat training zone with the Heat Ramp Test and this will help you train effectively.
Safety
The CORE sensor technology can be used effectively in sports to monitor core body temperature, guide effective heat training and to help avoid undercooling or overheating by taking preventative measures based on the real-time data.
Athletes should only train to their own individual thresholds and we encourage professional coaching and medical guidance for heat training. Please contact us if you wish to use the CORE sensor for use-cases / sport which are not yet validated.
