The CORE sensor is the first and only wearable that gives you continuous, accurate core body temperature monitoring so you can train and perform at your best.

• Continuous, accurate core body temperature monitoring
• Accuracy backed by clinical, lab, and field tests
• Automatically sends data to wearables + training apps
• ANT+ and Bluetooth compatible for easy pairing

Why use CORE?

The CORE sensor is the most accurate non-invasive wearable device for continuous core body temperature monitoring.

The sensor allows you to see how much your core temperature rises with effort, so you can train your body to adapt to internal and external heat.  You can also design personalized cooling protocols crucial to helping you sustain your power and pace on race day. 

• Understand how your core body temperature correlates with performance metrics.
• Real-time core body temperature on your watch / cycling head unit
• upload data to TrainingPeaks for further analysis
