Guide Review - Garmin Forerunner 305

Garmin is one of very few GPS makers to offer units specifically for running and cycling, but fortunately for fitness buffs, it takes the category seriously and offers a solid range of products that it continually improves. The Forerunner 305 is positioned just below the new-for-2008 Forerunner 405 in the Garmin line.

The Forerunner 305 will serve the needs of someone who wants to simply track time, speed, and distance in a basic running or walking program, but it also has enough features to satisfy the most obsessive enthusiast, and is great for someone who needs to share data with a professional trainer or coach.

The 305's display is all about choices. Using the unit's relatively easy to learn "mode," "enter," and "scroll" buttons, you can partition the display into as few as one large data display, or as many as four. When cycling, for example, I kept an eye heart rate, current speed and elapsed time.

The Forerunner 305 comes with a data dock that plugs into a computer's USB port, and this permits you to upload all of your training data into Garmin's Training Center software, or online to the Garmin Connect website. Storing and analyzing your workout data using these excellent graphing and sharing tools is one of the key benefits of using the 305.

The unit comes with a wireless heart rate monitor strap, computer docking/charging station, a separate charger unit, and the Training Center software on CD. Setup and installation went smoothly, but you will need to spend some time with the manual, and getting accustomed to the button functions.

A full set of time, distance, and heart rate zone alerts are completely customizable and will keep you in your desired ranges. You may also compete against a "virtual partner." Advanced workout options abound.

Excellent training instrument, Member aa_cohen

I've had the 305 for over a year now, running with it 3 times a week on average. This watch has changed the way I train in many aspects. The trivial ones are simply the real-time tracking of my pace, distance, heart rate and time. Using it, I found that I have an ever improving ability to tune my trining effort level to match my goals. The ability to track my training over time, comparing different tracks and different runs on the same track, is also a great plus that comes for free with the 305, and helps in better planning future training sessions. A neat feature that I started using lately is the ability to download tracks to the 305. You can design a track the length and profile you want on many map-based Web services (like MapMyRun.com), then load it to the Garmin. Using the map mode of the 305, you can see your track as you go, so you know when to turn and where to go - even in an area you never knew before!! You can also use tracks published by other users. The accuracy of the Forerunner 305 is excellent. I estimate it to be not more than 3-4 meters (10-13 ft.), based on many distance measurements that I've taken. From a user interface standpoint, the 305 is pretty basic - no dazzling controls or displays. I don't find it to be a big disadvantage, as it is pretty convenient to use, with straightforward logic. After over a year (and probably close to a 1,000 miles) of using this watch, I can say that it is very robust and reliable. I have had zero problems with it.
