What To Look For
The best GPS running watches are also the most accurate. For instance, the Garmin Forerunner model uses HotFix™ satellite prediction that detects the closest satellite nearby for fast, accurate results. The GPS receiver not only tracks a runner's physical location and maps out trails to follow but can also be used to track speed, pace and distance.
Besides the GPS receiver component in the watch, there are several other important aspects of a GPS running watch that makes it a good model. Many have a heart rate monitor, can store a runner's workout to be uploaded to a computer for tracking, and keep track of calories burned.
Common Pitfalls
A common pitfall when looking to buy a GPS running watch is cost--the watch is a significant investment. Mechanical problems with these watches include short battery life, technology problems and overheating. Overheating can be caused by a faulty watch or, in rare cases, extremely long workouts raise body temperature, which can cause a watch to overheat. Once a watch overheats, it can shut down and lose all data; indeed, the watch might break permanently.
Another pitfall is inaccurate or slow satellite positioning. If you're using a GPS watch to navigate or find location on trails in remote areas you may find yourself lost. Additionally, running in cities with tall buildings may affect GPS accuracy.
Where To Buy
GPS running watches can be found in many sporting goods stores, nationwide gym chains like 24 Hour Fitness and LifeTime Fitness, retail stores like Wal-Mart and Best Buy. At popular online retailers like Amazon.com, and on Best Buy's website, customers can order some GPS watches that may not be available in the retail store.
Sporting goods stores and the internet would be the best places to find the biggest selection of watch brands and models.
Cost
Most GPS running watches cost between $100 and $550. The Garmin Forerunner 210 model is the most affordable on the low end of that price range, but doesn't offer USB uploads to the computer. Suunto is the most expensive brand, with the X10 model coming in at the high end. The more expensive GPS runners' watches usually can be connected to a computer via a USB cable to upload data. The Garmin Forerunner 405 is one of these and is $350.
