PaceBrain accepts activity data from any GPS device or running platform:

• .FIT files: Garmin, Wahoo, and most GPS watches
• .GPX files: Universal GPS format, exported from Strava, Garmin Connect, and others
• .TCX files: Training Center XML from various platforms
• .CSV files: Manual activity logs and exports
• Manual Entry: Log activities directly in the app

Tip: Most running apps and GPS watches allow you to export your activities in these formats.

Our machine learning models analyze your training history, pace trends, and physiological data to predict your race performance across different distances. This includes:

• Predicted finish times for 5K, 10K, half marathon, and marathon
• Pacing strategies tailored to your fitness level
• Confidence intervals based on training consistency
• Real-time updates as your fitness improves

Deficiency analysis identifies gaps in your training that may be limiting your performance. We analyze:

• Training Volume: Are you running enough weekly mileage?
• Intensity Balance: Too much easy running? Not enough speed work?
• Recovery Patterns: Are you allowing adequate rest between hard efforts?
• Long Run Consistency: Building endurance appropriately?
• Cadence & Form: Biomechanical efficiency analysis

Based on these insights, PaceBrain recommends specific training adjustments.

Heart rate zones help you train at the right intensity for different goals. PaceBrain calculates personalized zones based on:

• Your resting heart rate
• Maximum heart rate (detected from activities or user-specified)
• Lactate threshold estimates from pace/HR data

The five zones are:

• Zone 1 (Recovery): Very light, active recovery
• Zone 2 (Aerobic): Easy conversational pace, base building
• Zone 3 (Tempo): Comfortably hard, sustainable effort
• Zone 4 (Threshold): Hard effort, lactate threshold training
• Zone 5 (VO2max): Maximum effort, interval training

You have full control over your data. In Settings → Privacy, you can:

• Set profile visibility (public, followers-only, private)
• Hide exact start/end locations of runs
• Control which health metrics are shared
• Manage connected app permissions
• Export all your data anytime
• Request account deletion

We may use anonymized, aggregated statistics for product improvement and research, but these cannot identify individual users. See our Privacy Policy for full details.

Try these troubleshooting steps:

1. Verify the file format is .GPX, .TCX, .FIT, or .CSV
2. Check that the file size is under 10MB
3. Ensure the file contains valid GPS or activity data
4. Try re-exporting the file from your source app/device
5. If still not working, contact support@pacebrain.com with the file

AI predictions improve with more data. Ensure you have:

• At least 4-6 weeks of consistent training logged
• A mix of easy runs, tempo runs, and workouts
• Accurate max heart rate set in your profile
• Recent race results or time trials recorded

If predictions still seem off after meeting these criteria, contact support with details.
