Garmin Forerunner 620
Garmin Forerunner 620 upon first inspection has so many levels of upgrade versus the Garmin 610 its hard to know where to begin. We like them all, lighter weight (a full ounce lighter than 610), ground contact time, super high resolution full color screen, run oscillation, recovery time, race predictor, water resistant to 50 meters and so much new stuff to go around.
It still has touchscreen, does pace, distance and heart rate but that is where the similarities stop. It even has a new hinged band to fit all sizes of wrists better.
As we expected, real-time connectivity got added to this watch, similar to the Bluetooth Smart features added the the Garmin Edge 510 and 810 this past Spring and this allows you to transfer your data wireless to a Smart phone, or in real-time to Facebook or Garmin Connect. The watch also added WiFi so you have your choice to data transfer wireless to PC, also.
This vertical oscillation while running feature is one that we are super excited about. All world-class runners if isolated on film have very little bounce, or vertical energy, going into their stride. It is all good, quiet upper body mid-foot running for world-class runners.
Up until now, there has never been a GPS running watch capable of telling you how much vertical oscillation you had. Typical oscillation is between 6 and 13 centimeters with lower numbers being more ideal, so now you can adapt technique to produce lower oscillation and greater efficiency.
So how do you use the information? Use the run oscillation on the watch in real-time and experiment with your stride to try and reduce the bounce.
RECOVERY - THE IMPORTANT MEASUREMENT
Training too hard when you haven't recovered isn't smart but how do you know if you have recovered from yesterday's training? While we still feel that taking your resting pulse every morning is the best way to gauge recovery, Forerunner 620 can be good confirmation of this.
Forerunner 620 has a recovery adviser, which is a set of features that estimate how much time you need to recover from your run so you can more easily assess how hard your next one should be.
Get Specific Recovery Time
This feature estimates your state of recovery immediately following a run and operates in a countdown mode until the next effort. It all depends upon how hard our efforts are. A short 5k might render a reading of 6 hours time whereas a marathon might register several days of recovery time depending upon how you came through it.
Provides a real-time assessment of your recovery in the first several minutes of a run. This looks at the early stage performance and data of a workout to assess how well recovered you actually are, which is great but we'd recommend planning workouts using resting pulse in the morning.
When used with HRM-Run, VO2 max estimates the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body weight at max performance. With the right type of training over time VO2 maximum should improve but to get precise figures on your VO2 max you really need to visit a University Human Performance Lab.
Projects your finish time for a given race distance based on the your current VO2 max estimate. The race time is idealized based on your current state of fitness and presumed proper training.
This watch still offers both audible and vibration alerts, but now it is water resistant to 50 meters, which is much better than the old 610 at IPX7. This means you can actually use the 620 in the swim leg of a triathlon and it won't be harmed. It's not a swim watch but the fact that you can wear it start to finish and get all your bike and run metrics opens up a new world of possibilities for this watch.
If you just need something simpler that offers up pace, distance and heart rate data then consider the Forerunner 220
