  • Connected features²: automatic uploads to Garmin Connect™, live tracking, social media sharing
  • Compatible with free training plans from Garmin Connect

It’s the next best thing to having your own personal running coach. Forerunner® 620 offers advanced features like recovery advisor, race predictor and VO₂ max estimate to help you train smarter and achieve new race goals. When used with the HRM-Run monitor¹, the 620 also provides feedback on running form by showing your cadence, ground contact time and vertical oscillation. For indoor training, the 620’s built-in accelerometer tracks distance, so you don’t need a separate foot pod.

It Knows Your Potential

Regardless of how long you’ve been running, you likely want to know how you can improve and objectively measure your fitness. Forerunner® 620 does just that by estimating your VO₂ max, which is a good indicator of athletic capability. Previously, the only way to know your VO₂ max was by paying for a lab test. When used with a heart rate monitor, the 620 crunches several pieces of data, like 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.

A colour gauge on the watch shows how your VO₂ max data compares to other runners of your gender and age range. Based on your VO₂ max estimate, the 620 can predict your race times for several distances. This can give you a time target for your next race, assuming you’ve completed proper training.

Rest Day or Run Day

Forerunner® 620 takes out the guesswork when it comes to planning your recovery time between hard workouts. Just like a coach, it learns you and 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.

When wearing HRM-Run, the 620 provides a recovery check, which is a real-time indication of your state of recovery within the first several minutes of your run. When you’ve completed a run, the recovery time shows how long before you should attempt another hard workout. Colour coding on the gauge makes it easy to interpret — green means you’re good to go. When you see red and a recovery time of more than 3 days, you might consider taking a rest day or just doing a light recovery run.

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 impact your running economy.

The HRM-Run has an accelerometer, which measures your torso movement as you run in order to compute these metrics. Cadence is the total number of steps you take per minute, left and right foot combined. Vertical oscillation is the degree of “bounce” in your running motion, measured in centimeters. Ground contact time is just like it sounds — the amount of time your foot spends on the ground during each running step, measured in milliseconds. A colour gauge makes it easy to see how your running dynamics compare to other runners.
