If our analysis of your Strava account data reveals that your FTP (Functional Threshold Power) or threshold heart rate is higher than what you entered during the initial setup, we will send you an alert to let you know and suggest that you verify the values in your athletic profile. As you progress through your training plan, you may receive similar alerts if we detect improvements in your fitness level. It's important to keep your athletic profile up to date so that your training plan can be customized to your current fitness level and goals.
