Product details:
Whether you're training for your first marathon or looking to crush a personal record, Forerunner 630 provides all the extensive data you need for training and racing. Forerunner 630 uses extended physiological metrics to help you get the most out of your workouts and feel confident with what you can accomplish when you toe the line. Once Forerunner 630 learns your lactate threshold through a guided test, you can apply it to your heart rate training when setting up zones. Overall training load, sleep, nutrition and general life stress play a role in how you will perform in a tough workout. To give you a better idea of what days you should aim for a tough workout or use as a recovery day, Forerunner 630 provides you with a stress score based off your heart rate. Performance condition is another feature that gives you an idea of how you will fare in a workout. As you run, this feature analyzes your pace, heart rate and heart rate variability to make a real-time assessment of your ability.
