Power Zones explained
Stryd’s Power Zones are different power ranges (based on your Critical Power) that provide guidance when training with power. Zones give you a general idea of what type of training falls within a power range, though the actual number you run at may be more specific. Power zones are broken up into five ranges:
An example of how to use zone 1 might be… a runner with a CP of 252 watts has a zone 1 range of 164 - 202 W. Their easy run may be approximately 190 W +/- 5 W, near the top of the zone, while a recovery run may be near the bottom of the zone at 170 W +/- 5W.
As you train with Stryd, use Power Zones to help guide your session after taking note of where you feel comfortable within each zone for a targeted intensity.
