Why we like the CORE 2 Thermal Sensor

Train Hot, Race Cool

CORE 2 transforms heat from a performance limiter into a training tool. By precisely guiding your heat training sessions, it allows you to generate powerful physiological adaptations—like increased blood plasma and VO2 max—that boost performance in all conditions.

Beyond a Simple Thermometer

The new Heat Strain Index and Heat Adaptation Score provide incredible context. You're no longer just seeing a temperature; you're understanding how your body is coping with heat stress and visually tracking your long-term acclimation.

Invisible Integration

The new smaller, lighter design is a huge improvement. It clips onto your existing heart rate monitor strap and just works, feeding critical data directly to the head unit or watch you already use without changing your workflow.
