How does TrainingPeaks evaluate the Training Stress Score when syncing my training via Suunto’s digital service?

TrainingPeaks evaluates the Training Stress Score and training load based on power, heart rate and speed data measured by your Suunto watch and your personal settings in TrainingPeaks.

To ensure your performance values are correct, make sure your weight, age, height, gender, threshold power, pace, heart rate values and zones are correctly setup in your Suunto watch, Suunto’s digital service and your TrainingPeaks account.
