Forerunner 620 has incorporated more generation to generation changes than any watch we have seen since we got in the business years ago. It's that good and it truly warrants anyone's attention who is interested in having all the best, most cutting edge features.
GET DATA WHEREVER, RIGHT NOW
You've got two options with the 620: 1.) Wifi if you'd like to download data at a coffee shop or to your PC and, 2.) Bluetooth Smart to transfer data instantly and, even in real-time, with a Bluetooth Smart enabled phone.
Never before has there ever been the opportunity to share so much data and information with someone else (think coach) who is thousands of miles away. Share with your friends too with real-time data transfer to Facebook or Garmin Connect.
HOW GOOD IS MY RUNNING EFFICIENCY?
Up until now, this has all been guesswork becaus eno other running device on the market measures the vertical energy against the forward energy. You see vertical energy is known as run oscillation and too much is wasted energy.
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.
REAL RECOVERY DATA
Training too hard when you haven't recovered isn't smart but how do you know if you have recovered from yesterday's training? Resting heart rate and recovery heart rate are two measures that allow you to know how hard you should train. Forerunner 620 has a recovery advisor, 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.
SPECIFIC TIME NEEDED FOR RECOVERY
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.
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 your VO2 maximum should improve.
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 strictly run and just need something simpler that offers up pace, distance and heart rate data then consider the Forerunner 220
