The Forerunner 620, with its thinner, sleeker design, is one of two new Forerunner series to come out this year. There are MANY new features added to this watch from the former Forerunner 610. It comes in Black/Blue or White/Orange and with or without the new HRM-RUN.
The new features of this model over the Forerunner 610 are
- High resolution color touch display
- Water resistant to 50 meters (swimmable) : Although you can swim with this watch, it will provide no swim data
- 10 hour battery life (up from 8 hours) and 6 weeks in standby mode (Time of Day)
- 3 additional Heart Rate Monitor Metrics along with the Training Effect from the Forerunner 610
- VO2 Max estimate : Based on thousands of tests, this estimated value should be within +/- 2.7%
- Recovery Advisor
- Race Predictor : Based solely on the user’s estimated VO2 Max, this feature will predict the user’s times for a 5K, 10K, Half Marathon and Marathon
- The new HRM-RUN strap functions the same as our previous heart rate monitor, but has an accelerometer built in to give 3 new Running Dynamics : Cadence, Ground Contact, Vertical Oscillation
- Just like the HRM-RUN and foot pod, the Forerunner 620 has a built in accelerometer. This is used to measure the user’s pace and distance while running without GPS (typically indoors) as well as provide running cadence without the need for a foot pod
Garmin is excited to announce that several new features are being added to the Forerunner 620 through a free software update. Two new activity profiles - “Race” and “Ride” - now make it easy to switch between activities, viewing the fields you want to see. With the “Ride” profile, support for cycling speed and pedaling cadence via Garmin speed and cadence sensors has been added. The new “Race” profile allows user to set up different data fields or settings for races vs training runs. When using these new profiles, activities are automatically categorized as running or cycling when uploaded to Garmin ConnectTM. To get these new features, update your device software free of charge using Garmin ExpressTM.

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 color 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. Color 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 color gauge makes it easy to see how your running dynamics compare to other runners.
Thanks to its wireless upload capabilities, Forerunner 620 can send your run data to our online community, Garmin Connect, without being connected to a computer. It can transfer the data through the Garmin Connect™ Mobile app on your smartphone. You can also set up one or more Wi-Fi hot spots, like your home and office networks, and the 620 will automatically sync with Garmin Connect when in range.
Additional connected features include live tracking, which allows your friends and fans to follow along and see your stats in real-time. You must have your phone paired with the 620 throughout your run to use the LiveTrack feature. You can also share your victories on your social media sites by posting updates through the Garmin Connect Mobile app. And, for real-time coaching as you run, the 620 is compatible with free training plans at Garmin Connect. By regularly connecting your watch to Garmin Connect, you'll also benefit from a faster GPS fix due to satellite data that will be sent to your device automatically.
With the use of the built in accelerometer in the new Forerunner 220 and 620, questions have come up on how does this work and how accurate is it.
These watches use a 3 dimensional accelerometer which measures movement in all 3 dimensions, just like our foot pod.
- Not to be confused or compared with a pedometer which just measures 1 dimension (or basically just counts steps)
There is no manual calibration for this. Every time you run outdoors with GPS, the accelerometer gets calibrated to your running style. Basically, a table is created on the watch for many different paces so the more you run outdoors with GPS and at different paces, the more accurate it will be when you run without GPS.
- If you have never run outdoors with GPS under 9 minute miles and then run on a treadmill at 7 minute miles, your accuracy will not be as good.
Because a person’s arm swing is not as consistent as their foot strike (you can’t skip a foot strike but you can miss an arm swing by drinking, scratching, giving the #1 sign to the driver that cut you off), you should generally see greater accuracy with a foot pod.
The accuracy of the different ways to generate speed and distance in order typically are
- GPS (typically well over 99% accurate)
- Foot Pod (typically around 98%)
- Wrist worn accelerometer (typically about 97%)
