Garmin Forerunner 205 Wrist-Mounted GPS Fitness Computer (010-00466-00)

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.

The Forerunner 301's heart rate monitor continuously tracks and records your heart rate so you can see whether you're training too hard or not hard enough. What's more, Forerunner 301 also displays your current heart rate zone, a range of heart beats per minute that helps you gauge the intensity of your workout and train more effectively. After a few intense runs, Forerunner's AutoLearn™ feature calculates your heart rate zones and automatically adjusts them as your fitness level improves.

Use Forerunner’s unique training tool, Virtual Partner®, to help you meet your training goals. Simply enter the distance and time or pace/speed you want to maintain during your workout. Virtual Partner appears on the Forerunner as a tiny runner that "runs" alongside of you, displaying your goal pace compared to your current pace — so you can see at a glance whether you're keeping up or falling behind. To complete your workout and meet your goal, just stay ahead of the Virtual Partner.
