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.

How you can use the CORE sensor

Advantages of monitoring core body temperature

Heat Training

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

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 for Performance

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.

Testimonials

I have been implementing indoor training with professional cyclists for many years now. Now, to be able to monitor and assess this metric with CORE, our training will go to another level.

Kevin Poulton - World Tour coach, product manager for MyWhoosh

It is clear though from my testing that my body temperature goes up and down at the exact moments I expect it to. (...) if you’re training in hot environments for hours on end – then it makes more sense.

DC Rainmaker reviews technology for runners, cyclists and triathletes

The riders are extremely interested in the measurement and we see really a big GAMECHANGE here if we are able to have the body temperature available all the time during trainings and races.

Dan Lorang - Head of Performance and Head Coach @Borahansgrohe

The reason why we’re measuring the core temperature all the time is to get a better understanding of the intensity versus the output. The core temp is increasing at a high intensity in the same way we can see how the heart rate is ramping up.
