GPS stands for Global Positioning System, a satellite navigation system that provides location and time information wherever you are in the world. GPS running watches will know accurately the distance, speed and any elevations gained or lost during your run. They are extremely valuable if you want to set and monitor your pace whilst running or afterwards when you can connect to your computer and upload all the information for an overall view of your session. It will show satellite maps, splits, elevation, pace and time. If you are training for a race, whether it’s a 5k or a Marathon, or even for personal challenges, a GPS watch will allow you to analyse and measure your progress accurately.
