The Stryd platform will calculate your critical power automatically based on your running data .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.
Auto-calculated Critical Power is recalculated each time a run is uploaded into our data store. Your Critical Power will only increase if you run at a higher power level for a certain time than you did in the last three months for the same time interval. After three months, your runs are no longer considered when calculating Critical Power .
For example, I ran a 5k race in 20 minutes on the 1st of October. Any 20-minute effort after my race will likely be ignored until January since I am unlikely to run at race power in my regular training.
If you feel your auto-calculated Critical Power is incorrect, you can reset your auto-calculated Critical Power calculation and start anew (it will take 3 runs for the system to give you a new Critical Power number).
