Garmin Forerunner 205 Wrist Worn GPS Personal Training Device

Just when you thought Garmin had cornered the market on powerful, affordable, and effective wrist-mounted GPS devices, here comes the Forerunner 205. The release of this device is a major achievement from a design and technology perspective. This isn't just marketing-speak; the Forerunner 205 is the most accurate, most reliable wrist-mounted performance and GPS tracking tool we've ever tested. Yes, it's that good. While no device this compact can do everything (yet), the 205 pushes the boundaries of what is possible from something strapped around your wrist. While the 205 doesn't offer heart rate monitoring, or connectivity with Garmin's wireless speed and cadence sensor -- for that, you'll need to step up to the Forerunner 305 -- but it's a great way to get basic GPS location and performance data.

Design
The 205's design is a radical departure from Garmin's previous generation of wrist mounted GPS devices, which reached a pinnacle with the Garmin Forerunner 301. The 301 deliveres accurate heart rate monitoring, good performance tracking, and decent GPS reception.

The curved casing allows the unit's antenna to face the sky when you're running, while the widescreen display is perfectly positioned for viewing when you need it. And the display certainly deserves a few kudos. While it's smaller than the display found on previous Forerunners, its resolution is far higher, offering incredible clarity and crispness.

The 205 has a simple button layout and the buttons have a nice tactile feel with good pressure response. The right side houses the menu selection and enter buttons, while the left houses a power/backlight button and a mode button. This simple and elegant solution is a big improvement over the sometimes confusing button functionality of previous Forerunners.

The underside of the 205 has a row of contacts that interface with the included charging and data cradle. The cradle is small and unobtrusive and its single mini-USB port connects to either an included AC adapter, or a USB cable that connects to your PC. In addition to data transfer with the USB cable, you can also charge the 205's embedded lithium-ion battery via a powered USB connection from your computer.

GPS Performance
The big news about the Forerunner 205 is that it features an integrated, high-sensitivity SiRFstar III GPS receiver. What does this mean? It means that the 205's ability to both track, and maintain a lock on, your position is better than anything before it. After an initial battery charge, our product tester had the 205 on his wrist and was tracking speed and distance with GPS satellites within 3 minutes. The next time we used the 205, satellite acquisition was nearly instantaneous. A run through dense trees didn't faze the unit either; tracking remained true and steady. Performance on a bike was equally impressive.

The simple docking cradle makes charging and data connectivity a snap (Forerunner 305 model shown).

While the Forerunner 205 isn't billed as a GPS navigation device, it does have some good mapping, waypoint marking, and routing capabilities. In addition to marking locations along your journey, you can zoom in or out of a simple map that displays your current direction and path. There's also a "go to location" feature that routes you back to your starting location, or to any location you have defined. Once you have defined several locations, you can save this information as a route, allowing you to travel the same path in the future. As you'll see below, the 205's new "Courses" feature gives you new levels of control over how you define your favorite runs and rides.

Training Functions
The heart and soul of the 205 can be found on the data screens, which give you real-time information about all aspects of your workout. In fact, the 305 can display a dizzying array of data, such as calories burned, distance, elevation, grade, and heading, as well as multiple lap and pace modes.

Garmin's Virtual Partner function is a great feature of previous Forerunners and they've decided to keep a good thing going with the 205. If you're the type that performs best when you've got a competitor egging you on, you'll love this function, as it allows you to set up virtual running or biking companions that compete against you.

If you're looking for a complicated workout with a variety of intervals and intensity levels, or just a quick three-mile jog against your best time last week, the 205 has you covered. Navigating to the Workouts menu on the device yields three options: Quick Workouts, Interval, and Advanced Workout. A quick workout is just that; set the distance and time, distance and pace, or time and pace of your planned workout and off you go. Interval workouts are just the same, but they allow you to add repetitions and rest between them. When you really want to get fancy with your exercise, you can step up to advanced workouts, which include goals for each workout step, as well as varied distances, times, and rest periods. You can use the Garmin Training Center software to set up these workouts and then upload them to the device.

PC Connectivity and Software
Garmin has been outfitting their devices with USB connectivity for some time now -- a welcome move for those who struggled with serial port connections in the days of yore. Thanks to USB, the 205 integrates seamlessly with the Training Center software and we quickly had workout history uploaded and stored on the PC (Sadly, Training Center is not Mac-compatible).

In a first for the Forerunner series, the Training Center software also lets you define courses on your PC that you can upload to the device. When course information is combined with uploaded workout information, the Forerunner becomes a complete guide, telling you where to go, when to make a turn, and what kind of workout to do when you're on the road or path. Back on the PC, the software's ability to overlay workout data on maps of the course makes it easy to see where the course offers up the tough hills and the easy recovery spots. Plus, the ability to track historical performance on a given course is a great way to measure your improvement.

The 205 is also fully compatible with Garmin's MotionBased service, which takes your training to another level by connecting your data with the Internet. While we weren't able to use the service, the promise of sharing courses, maps, workouts, and performance data with other users is intriguing. And if you're a serious endurance athlete, you'll be glad to know that the 205 is also compatible with TrainingPeaks.com, an easy-to-use web based training system designed to help athletes train for any event.
