Deeper signals reaching out from the depths of the body

While skin temperature reflects the surface of the body, core body temperature reveals changes in internal heat. By combining heat flux sensing, skin temperature, and physiological modeling, the Speediance Strap provides information to better understand how your body is responding to training, heat stress, recovery, and sleep.

* Incorporates "Calera®," a core body temperature measurement technology developed by the Swiss temperature sensing company, greenteg.
Peak performance hours

Peak performance hours

Not every time of day is equally suited for high-intensity performance. Changes in core body temperature and your circadian rhythm can help you identify the times that may be better suited for high-intensity training.

Warm-up ready state

Warm-up ready state

Just because you are sweating, it does not necessarily mean your body is in a state to perform at its best. You can check your body temperature response to determine whether you should continue your warm-up or move on to the next phase.

Heat stress monitoring

Heat stress monitoring

Just because you feel hot doesn't mean the quality of your training has improved. Track the increase in heat load and identify the right time to adjust your pace, recovery, and hydration.
