CORE - Core Body Temperature

CORE fits right into the next dimension of training -- what your current workload is doing to your body, and how can you manage it. It winter here now, so racking up the data. My key races are in the heat of the summer, and as a 81kg athlete I pay a heavy price on the run. The CORE will be an integral part of preparing for those conditions and executing in them as well. Don't wait!

I have only used the CORE Sensor and App version 2.2.2 for a few weeks. It seems greatly improved from the other reviews I see here. It shows Fahrenheit or Celsius. I have mine set to Fahrenheit. I recommend getting familiar with the Sensor with one’s HRM Strap by wearing it around the house or while sleeping to see the baseline resultsover several hours or 12 hours. The rechargeable battery life seems to last, in other words, it drains slowly. The two devices must be turned on the watch settings to get the HRM data to flow (download) to the CORE App. I am using it with a Garmin EPIX Gen2 Watch and the Garmin HRM-Pro Plus Running Strap (with Ant+ and Bluetooth). The CORE Sensor pairs to the HRM which communicates both via Ant+ to the watch. Both the New Garmin HRM-Pro Plus and the CORE sensor can communiate to the CORE App so the App can download the Heart Rate Data from the HRM Pro Plus and the CORE Temp and Skin Temp. These are graphed in the App. I have the CORE data-field on one of my Run, Track Run, Treadmill Data Screens. Because the EPIX has a outside temp sensor, I put that field on a separate screen to understand the difference between my CORE temp and the outside temp the watch detects. From my reading, Heat Temp training is akin to Heart Rate Training. If you train at an elevated CORE Temperature at few times a week, one’s running or biking performance, this greatly improves performance and Temp awareness and its impact on Pace and endurance. I bought it to better understand the CORE temp zones and not to exceed the sweet spot which ultimately degrades performance. I watched a number of CORE YouTube Videos. As an older runner I also wanted to know my CORE Temp when training outside on hot days or during a summer half marathon so as not to injure myself. I am starting to experiment with the levels on a treadmill. I am also starting to use the Airofit Respiratory Trainer to improve my breathing, proper breathing and expanded lung capacity can help with reducing CORE Temp to get to the right CORE Zone Temp. The Sensor seems to do that but I admit I am a novice with this type of training but it is one more tool in the Tool Box. One recommendation I would make is to modify the datafield into a gauge on the watchface similar to the Garmin heart rate zone Gauges in style, this will create a uniformity in flipping screens on the watch since I monitor Heart Rate Data. I would give it five stars if they had a CORE Temp Zone Gauge on the Garmin th

Had issues with some of the sensors and am unable to fetch the data.

App works ok, wish that there was more information about how to use the device in the app, and that you could export a record of your temperature. But the fact that there is an option in the settings to change from Celsius to Fahrenheit and that the option does nothing is oddly upsetting. Wish it worked.

Can't change units to Fahrenheit and occasionally switches from the temp monitoring screen back to the main screen and loses the temperature history.
