If you are a serious runner or professional athlete, then purchasing a GPS running watch comes highly recommended. With the improvement in the navigation technology, the latest watches are far more advanced and far better performers than the ones that were sold even a few short years ago. With almost instant satellite connection, they could pinpoint your location with a few meters accuracy, measure your speed, the covered distance, and help you make the best out of your workout.
Coupled with a few accessories such as heart rate monitor or foot pods, they are also ideal for cyclists and many other sport enthusiasts. However, before purchasing a GPS running watch, you should carefully weigh your own needs instead of going for the most expensive model off the bat: some of them are water- and weatherproof, and ideal even for swimmers and skiers, while others have advanced functions that trail runners could find useful. There are models, which have number of functions that also allow you to collect most of your data even when you train indoors. Before making a purchase, you need to find out more about the functionality of the model that you are considering, its ease of use, and its performance. Larger in-built memory would allow you to store and, later, analyze more data, while longer-life battery would give you longer uninterrupted performance.
Other specifications such as dimensions, weight, screen size, display resolution, number of screens, and customization could be of importance to you as well. Take the time to understand the various different functions that the GPS watches come with, read a number of reviews, and purchase the one that would help you train better than ever.
