Train and race with real-time
Core body temperature affects performance and safety
As you heat up, your power and pace decline.
The CORE sensor helps you to adapt and improve your performance when you get hot. Easily integrate CORE data into your existing training to unlock your full potential on race day.
Advantages of monitoring core body temperature

More effective and precise heat adaptation and acclimization to condition your body for better performance.

Strategic cooling suited to your individual temperature behaviour on race day.

Set your own safe limits to maximise performance while avoiding overheating.
Real-time data and trends
Train more effectively and stay in control when you race with real-time core body temperature data and trends.
Used by top athletes and teams
Why CORE?
Up to now, core body temperature could only be measured continuously using invasive methods like thermometers, probes and electronic pills or in a controlled environment.
The CORE sensor is the first wearable device that continuously and accurately measures core body temperature on the go.
The CORE sensor seamlessly integrates and lets you see your live data on the Smart Phone App and record directly to Garmin, Wahoo and COROS. Learn More

HEAT TRAINING
How to use Heat Training and the Heat Ramp Test for sports.

Heat affects performance
“In long distance running events, the ability of bodies to maintain or regulate heat is what ultimately determines how long athletes can last at a given intensity, along with their internal energy state and their fitness,”
– Peter Vint, High Performance Sport Expert
Temperature verses speed
With an environmental temperature of 10°C/50°F, our runner can finish a marathon in 3:30.
For each 5°C/9°F increase in outside temperature, the runner needs an extra 5 minutes to finish.
Why Core body temperature matters in sports
No more guessing how hot or cold you are, with the CORE sensor and accurate measurement data you can train and race more effectively.
CORE's role in the Filippo Ganna UCI Hour Record
Filippo Ganna of team INEOS Grenadiers set the current UCI hours record of 56.792 km with the support of past hour record holder Dan Bigham and from the experts at CORE.
