Garmin 100112841 Forerunner 620 GPS Watch White/Orange

It Knows Your Potential

Forerunner 620 can estimate your VO2 max, your body’s maximal oxygen consumption. Knowing your VO2 max is a great way to measure your physical fitness and improve your performance. When used with a heart rate monitor, the 620 crunches data, including your running speed, beats per minute and heart rate variability to estimate your VO2 max. The number itself indicates the maximum volume of oxygen you can consume per minute, per kilogram of body weight at your max performance.

Rest Day or Run Day

With Forerunner 620, you don’t have to guess how much recovery time you need between workouts. It knows your physiology based on your heart rate data, so it factors this against your last workout and then shows how much time before you are fully recovered and ready for your next hard running workout.

Following Your Form

The 620 is the first GPS running watch that provides feedback on your running form by reporting multiple metrics. When used with the HRM-Run monitor¹, the 620 reports your cadence, vertical oscillation and ground contact time. These metrics are called running dynamics, and they effect your running economy.
