Buying Guide for Runners: How To Choose The Best Running Watch?

Running has grown popularity in the past few years. There are now more people who understand that having an active lifestyle has a huge impact on our health. Although, there are plenty of exercises and sports to choose from, running is simply the simplest and still the most popular way to get fit.

Why do you need a running watch?

While smartphones nowadays have apps you can use when running, a running watch displays real-time tracking information right on your wrist. Using a running watch not only takes out the hassle of running with a phone in your pocket but also provides you with longer battery life and more accurate running data.

Running watches basic features include tracking your distance, speed/pace, and calories. Advanced features can be anything from heart rate monitoring and interval session programming, to running dynamics and full-route navigation. Latest models also let you choose from wide range of watch faces and allow you to control music from your phone.

For people who are just starting to run or those who already incorporated running into their lifestyle, a running watch can provide some source of motivation to stay on track by giving you goals to achieve and alert you when you hit a milestone. For runners who have taken this activity seriously to a professional level, like triathletes and marathoners, a running watch will be the best tool to record and analyse running performance. Data gathered during a run can then be used for find ways on how to improve your running form.

Obviously, the more features you get, the pricier the watch gets. But not all of those extra features might be necessary for your running needs. To help you find the best running watch suited for you, here are the top 4 factors you need to consider.

How would you use it?
Would you use it for sports other than running?
Would you like to have a heart rate monitor feature?
Would you like to pair it with your smartphone to receive notifications or alerts?
Would you like to pair it with Garmin Running Dynamics Pod?

Cadence is the number of steps per minute. It displays the total steps (right and left combined).

Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.

Stride length is the length of your stride from 1 footfall to the next. It is measured in meters.

Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step.

Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form.

Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.

The following GPS running watches are compatible with the Garmin Running Dynamics Pod:
