The large display--with equally large, easy-to-read characters--helps you avoid having to squint at the readout. Just a quick glance at your numbers and you'll maintain your training concentration. The six rubber buttons on the front of the chassis are easy to access (unless you're wearing bulky gloves). I easily got the promised 13 hours out of the rechargeable lithium-ion battery. At the end of the day, I'd just recharge it for around two hours and it would be ready for me the next morning.

While this is definitely a workable GPS receiver, the Forerunner is slim on overall GPS features--which is not to its detriment (think of it as a performance monitor with a dash of GPS). That said, the Forerunner was able to pick up a GPS signal just about wherever I went outside (though it had very slight hiccups in the center of downtown). But if you're looking for a full-fledged tracking device, the Forerunner isn't for you. (You'll want to start with a basic GPS unit like Garmin's eTrex.)

The Forerunner 201 has a variety of helpful tracking, monitoring, and navigational features. The History function enables you to view your workout statistics broken down by individual days, cumulative weeks, or your entire workout history (if you track different workouts during the same day, they'll be broken out as different laps). You can even view a map of your route. And much like other GPS units, you can save waypoints (called "locations" in Forerunner parlance) to mark the coordinates of a place you want to return to later.

Most interesting is the Virtual Partner mode, which enables you to set goals for a workout which will then be completed by a digital character displayed on the Forerunner's screen. You can then see how far off the time, pace, or distance you are of your virtual training buddy's; your digital character even stops when you do (though the buddy keeps on going). I found that, unless you've got a good idea as to your pace or distance, you'll have a couple of trial-and-error training sessions to get in sync with your buddy. I cut short my first attempt after my buddy got so far ahead of me that he disappeared off the screen (which I'd like to believe was not due to my woeful pace).

I was disappointed at not having the LogBook software, which enables you to keep a journal of your exercise activities (it was not available at the time of this test). But overall, the Forerunner 201 is a very useful exercise-monitoring system that will be prized by anyone involved in serious physical training. --Agen G.N. Schmitz

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."

Pros:

• Loaded with performance-tracking features for the serious athlete
• GPS functionality a bonus, especially in referring back to previous routes
• Virtual Partner feature offers a fun, competitive way to keep you concentrated on training

• Lack of Logbook software at time of test
• Virtual Partner feature takes some trial-and-error adjustments

I went on a five-mile run and the unit was amazing. I did not lose signal once. It gave me my time, pace, distance ran, calories burned, and average pace. I am extremely impressed with this unit.

I am looking forward to the release of the software that will allow me to track all of my running statistics. The Forerunner adds a new dimension to running.

I now highly recommend it.
