Click the "Connect with Strava" button and follow the authorization process. We'll securely access your activity data using OAuth.

We need at least 28 days of training data to provide accurate divergence analysis. This gives us enough data points to identify patterns in your training load and internal stress levels.

If you don't have 28 days of data yet, we'll show you a preview of what your analysis will look like and guide you through building up your data history.

Data processing typically takes 2-5 minutes depending on the amount of activity data. You'll receive an email notification when your analysis is ready.

Yes, we take data security seriously. We use OAuth to securely connect to Strava, never store your password, and follow industry best practices for data protection.

Divergence analysis compares your external training load (distance, time, elevation) with your internal stress (TRIMP from heart rate). When these diverge, it indicates potential overtraining or undertraining.

Positive divergence means your external load is higher than internal stress (good fitness adaptation). Negative divergence indicates potential overtraining risk.

TRIMP (Training Impulse) measures your internal training stress based on heart rate data. It's more accurate than just distance or time because it accounts for how hard your body is working during each workout.

Training Load Divergence Analysis is our patent-pending innovation that combines four-dimensional parameter analysis: external work (distance + elevation) vs. internal load (heart rate TRIMP), analyzed across acute (7-day) and chronic (28-day) time periods.

This breakthrough methodology calculates a normalized divergence between your external mechanical demands and internal physiological response, providing unique insights into training adaptation, injury risk, and performance readiness that traditional single-metric systems cannot detect.

By measuring the relationship between what you're doing (external work) and how your body is responding (internal load), our system acts as an objective inner voice that helps you make confident training decisions without second-guessing.

While heart rate data provides the most accurate TRIMP calculations, we can still provide valuable insights using estimated heart rate zones based on your activity type and perceived exertion.

We recommend checking your analysis weekly to track trends and make adjustments to your training plan. The dashboard updates automatically as new activities are synced from Strava.

AI recommendations are suggestions based on your data patterns. Always listen to your body and consult with a coach or healthcare professional for personalized training advice.

Go to Settings and configure your resting and maximum heart rate. We'll automatically calculate your 5-zone system for accurate TRIMP calculations.

ACWR (Acute:Chronic Workload Ratio) thresholds help identify injury risk. We use industry-standard ranges but you can customize them in Settings based on your training experience.

The AI Journal analyzes your subjective input, training notes, and objective data to provide personalized insights and recommendations for your training success.
