Garmin GPS Forerunner 301:
The Garmin 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. The Forerunner 301 has three separate sport modes for running, biking and another activity. Just press and hold the mode button to switch between sports and record your run, ride, hike or other workout. You can also use Forerunner 301 to train for your next duathlon or triathlon with the multi-sport setting. This feature lets you seamlessly transition between sports without resetting the unit, so you can include running, biking and another sport, all in the same workout.
