Form meets function with Garmin's high-performance line of personal trainers - the Forerunner 205, 305 and 405. The Forerunner 205 includes a high sensitivity GPS receiver and a new courses feature for optimal performance. The Forerunner 205's courses feature lets you compete against previous workouts: you can compare your pace over your entire workout to your past performance over the same run. You can also use Forerunner 205 to train for your next duathlon or triathlon with multi-sport workouts, a feature that lets you seamlessly transition between sports without resetting the unit, so you can use it for running, biking and more.
