My Garmin 305 is awesome. It makes training so much more productive. Instead of having pre-measured running routes and distances, you can simply start running and it tells you the distance, pace, time, heart rate, lap pace and so much more. You can program several different types of workouts, intervals, paces and distances easily. You can customize different pace intervals and heart rate intervals to your specific settings. Initially I had a problem with the pace fluctuating too much to be useful. The Garmin customer support were very friendly and after changing the setting to “most smoothing” I am satisfied. I would recommend this product to anyone training for a run.
