The handiest running extra you can ever have. Would you like to know where you have ran, your heart rate, your calories, your incline and your speed! Well now you can. I was told about the Garmin watch recently and I was amazed by the accuracy and the quality of the watch. As it uses GPS signals to plot where you have been and to calculate your speed. Calories are calculated through your weight and heart rate so almost spot on, much more precise than your normal machine.
The watch has also taken its technology a stage further by being able to record sunrise, sunset, laps to go and pace. There is a custom workout setting on the Forerunner 610 which allows storage of your workouts, including how far, how fast or how long you want to run. This will build a different route with intensity levels and rests. There is even a chance for you to do interval running simply and effectively.
