Viewing Your Predicted Race Times
For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile), and set your maximum heart rate (Setting Your Heart Rate Zones).
Your watch uses the VO2 max. estimate (About VO2 Max. Estimates) and your training history to provide a target race time. The watch analyzes several weeks of your training data to refine the race time estimates.
TIP:
If you have more than one
Garmin® device, you can specify your primary training device in the
Garmin Connect™ app, which allows your watch to sync activities, history, and data from other devices
(Syncing Activities and Performance Measurements).
