greenTEG CORE Body Temperature Sensor

Item number: 85286

The CORE Body Temperature Sensor by greenTEG improves your temperature management

With the CORE body temperature sensor by greenTEG you add an often overlooked component to your performance data - your body temperature. The chest sensor is so light that you won't feel it while it sends you information that helps you manage your fluid intake perfectly. This is particularly interesting for indoor training, as you overheat more quickly due to the lack of airflow. So regulate your training intensity, active cooling and hydration to stay extra powerful. Simply attach the temperature sensor to the chest strap of your heart rate monitor or use the included patches to position the CORE correctly.

The Heat-Stress-Test allows you to determine your optimal performance temperature. On average, performance drops rapidly at a core body temperature of 38.5 °C. This is why even professionals now widely rely on temperature measurements during training and competition. 19 out of 23 professional teams at the 2021 Tour de France tracked their body temperature using the CORE sensor. What's more, the CORE also contributed to victories in road cycling at the Tokyo Olympics.
