Although it lacks the rechargeable battery and PC connectivity features of the Forerunner 201, the 101 retains all of the other great features of the 201, at an even more affordable price. The Virtual Partner feature allows you to set your training goal by configuring your Virtual Partner's pace and workout distance. You'll get a graphic perspective of your performance by viewing your pace in relation to your Virtual Partner's pace, so you can always see at a glance if you're keeping up or falling behind.

Almost as important as the training device itself are the accessories to integrate it with your active lifestyle. If you're into cycling, the best way to keep an eye on your GPS while you ride is with a bike mount bracket that straps to the handlebars of your bike, motorcycle, or whatever you're traveling with for easy viewing.

Other Forerunner 101 features:

• Mark specific locations, and then look-up and navigate to these points using an electronic map.
• Amount of calories burned can be tracked and calculated over the course of a workout.
• Lap history--such as lap time, lap distance, and average pace--can be stored for 5000 laps.
• Performance data can be automatically archived and calculated to provide an accurate record.
• Automated stopwatch provides auto-lap and auto-pause features.
• Pace whistle sounds alert when you begin traveling slower or faster than your desired pace.
• Time and distance whistles can be set to sound when you reach a specified duration or distance in your workout.

Auto Menu: Timer pauses when you stop running. Auto lap logs your performance over a predetermined distance.

History: Review training history by day or week.

Map: Navigate back to the start or to a stored location.

Virtual Partner: Set time, pace, and distance goals, and train with a "virtual partner."

The easy-to-use, water-resistant sensor calculates its position by measuring the distance between itself and three or more GPS satellites. Note that GPS positioning requires satellite visibility to work, thus it will only work reliably outdoors, and not in valleys between tall trees and buildings. GPS signals also rely on radio frequencies (RF), and therefore won't go through metal or water. The G1, which works with AA batteries, offers a battery life of up to 10 hours in warm conditions or up to 15 hours in low-power mode. The sensor also weighs a lightweight 2.82 ounces.

About Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.
