Why is my RSS value 0 in PowerCenter?
Updated over a week ago

PowerCenter calculates various metrics and training plans based on your critical power. Critical Power (threshold power) represents the highest power that a runner can maintain in a quasi-steady state without fatiguing, where the duration may range from 30-70 minutes, depending on the individual. You can read more about Critical Power here:

If you use the default settings of the Stryd system, Stryd will automatically calculate your Critical Power number based on your run data. You will get an initial estimate of your Critical Power after three runs. As long as critical power is not is set in PowerCenter (i.e. 0), your RSS values will be 0 since power is critical to determine your RSS. RSS is a single number to help runners understand their day-by-day training. It takes into account the volume and intensity of your training session to give you a single number, or “score.”
