Garmin Forerunner 620 Review

Forerunner 620 is an advanced running watch with a color touchscreen and offers features like recovery advisor, race predictor and VO2 max estimate (we’ll cover these later on). This is a serious running watch aimed at runners that want maximum data from their training or those runners that simply want the latest and best wearable tech.

Forerunner 620 is a considerable upgrade to the previous Forerunner 610 which also had a touchscreen but was very clunky to navigate, the 620 is easy to navigate and scroll through the screens (even with sweaty fingers or gloves).

Garmin Forerunner 620 key features

  • Tracks time, distance, pace, heart rate (with HRM run monitor) and calories burned
  • Built-in accelerometer and GPS tracks distance and pace, indoors and out
  • Running Dynamics: pair with HRM-run to measure cadence, vertical oscillation and ground contact time
  • Advanced fitness metrics: pair with HRM-run for VO2 max assessment and recovery analysis
  • Sync with WiFi or Bluetooth Smart to upload and share your runs online

When paired with the Garmin HRM-Run, Forerunner 620 adds feedback on running form by showing your cadence, ground contact time and vertical oscillation, or degree of bounce.

The 620 also has connected features like automatic uploads to Garmin Connect, live tracking and social media sharing so you can promote your achievements to your friends. With high-resolution touch-screen display, the Forerunner 620 is a GPS running watch that does more than just measure essential running data like distance, pace, and heart rate. It’s like having a coach, trainer, and analyst on hand to give you feedback as you run.

Improve your running form

Forerunner 620 captures a wealth of data that gives runners a detailed insight into their training and where they can improve. We would recommend purchasing the Heart Rate bundle option as pairing with the HRM gives you Running Dynamics.

This isn’t the average heart rate monitor that Garmin offers but the HRM-run version which has a built-in accelerometer to measure torso movement and running form. The Forerunner 620 ‘Running Dynamics’ is what separates the 620 and it’s competition. Running Dynamics includes the following extra features:

Customize the FR620 screen with different data fields.


This feature counts total steps (right and left combined). A typical cadence is between 150-200 steps per minute, with 180 steps being the sweet spot.

Ground contact

Forerunner 620 (Amazon) measures how much time, during the running motion, your foot is on the ground rather than in flight. Ground contact time is measured in milliseconds. Most running ground contact times are between 160-300 milliseconds. Elite runners typically spend under 190-milliseconds in contact with the ground each step.

Vertical oscillation

This shows the degree of ‘bounce’ in your running motion. Vertical oscillation is measured in centimeters from a fixed point on your body (sensor on the chest mounted HRM-Run monitor) typical oscillation is between 6-13 cm. Elite runners generally oscillate less.

VO2 max

Estimates the maximum volume of oxygen (in MM) you can consume per minute per kilogram of body weight at max performance. VO2 max is an indication of aerobic capability and should increase as your fitness improves. Recovery Advisor: Estimates how much time you need to recover from your run. And at the start of the next run, provides a real time assessment of your recovery so you know how hard you can go.

Bluetooth connectivity and Garmin Connect

The Forerunner 620 comes with a magnetized USB charging cable that the watch snaps into. Unfortunately, the cable is bespoke to the 620 so any other charging cables won’t fit the device. We hope in the future Garmin standardize their USB cables. Once connected to your desktop computer (PC or Mac) you’ll need to download Garmin Express, this is the free application which syncs and updates your Garmin device (not to be confused with Garmin Connect).
