A Deeper Signal, Straight from Your Core

Skin temperature reflects the surface, core body temperature reveals the heat trend within. By combining heat-flux sensing, skin temperature, and physiological modeling, Speediance Strap adds deeper context to how your body responds to training, heat, recovery, and sleep.

*Developed by Swiss thermal sensing company greenteg's Calera® core body temperature technology.

Peak Window

Not every hour of the day is equally suited to high-intensity performance. See when your core temperature trend and circadian rhythm may be better aligned with higher-intensity training.

Warm-Up Readiness

Sweating does not always mean your body is prepared for higher output. Follow your temperature response to understand when to continue warming up or progress.

Heat Load Monitoring

Feeling hotter does not always mean you are training better. See when heat load is rising and when it may be appropriate to adjust pace, recovery, or hydration.
