Just when you thought Garmin had cornered the market on powerful, affordable, and effective wrist-mounted GPS devices, here comes the Forerunner 305. The release of this device is a major achievement from a design and technology perspective. This isn't just marketing-speak; the Forerunner 305 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 305 pushes the boundaries of what is possible from something strapped around your wrist. The 305 model includes wireless heartrate monitoring and it can also be connected to Garmin's wireless bicycle speed and cadence sensor. If you don't need these features, consider the lower-priced Forerunner 205.

Design
The 305'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. While the 301 delivered accurate heart rate monitoring, good performance tracking, and decent GPS reception, it didn't quite deliver in the design department. The form factor was bulky and wearing it wasn't much different than duct taping a full-sized GPS device to your wrist.

Not so with the 305. Garmin's engineers obviously burned the midnight oil and have come up with a waterproof design that, while certainly not as small as a sports watch, feels just as comfortable. 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.

Garmin has smartly given the 305 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. View button layout.

The underside of the 305 is pretty nondescript, except for 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 305's embedded lithium-ion battery via a powered USB connection from your computer.

GPS Performance
The big news about the Forerunner 305 is that it features an integrated, high-sensitivity SiRFstar III GPS receiver. What does this mean? It means that the 305's ability to both track, and maintain a lock on, your position is better than anything before it. After an intial battery charge, the tester had the 305 on his wrist and was tracking speed and distance with GPS satellites within 3 minutes. The next time we used the 305, 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. Whatever witchcraft has been cooked up by the designers of the SiRF technology, we like it!



The simple docking cradle makes charging and data connectivity a snap.
While the Forerunner 305 isn't billed as a GPS navigation device, it does have some rudimentary 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 305's new "Courses" feature gives you new levels of control over how you define your favorite runs and rides.

Training Functions
The 305 is first and foremost a training tool, and its ability to organize a ton of data types into a user experience that is intuitive and simple is no small feat. Whiz-bang technology aside, if you can't use it and make it a natural part of your exercise routine, it's worthless. When it comes to these factors -- and here's the take home message on the 305 -- this device is successful where many other devices fail.

The heart and soul of the 305 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. The 305 adds the ability to track heartrate, lap heartrate, average heartrate, and heartrate zones via the included coded heartrate chest strap. With the purchase of a separate wireless cadence and speed meter, you can also track bike performance data.

Thankfully, the device makes it easy to define how much or how little data you want to view during a workout. You can arrange the data that's most important to you and then make that data appear front and center on the device. Indeed, within a few minutes of skimming the manual and fiddling with the device setup, you'll have your most important data displaying just the way you like it. The ability to display heartrate is a big plus, too, as it's a fairly good indicator of excercise output, fatigue, and fitness level. The 305 has all the heartrate functions you'd expect from a full-function monitor, including the ability to set target zones and alerts to maximize the effectiveness of your workouts.

Garmin's Virtual Partner function was cool feature of previous Forerunners and they've decided to keep a good thing going with the 305. 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 an complicated workout with a variety of intervals and intensity levels, or just a quick three-mile jog against your best time last week, the 305 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 305 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). Not only does Training Center make it easy to track your performance, you can graph data such as heartrate alongside your speed and distance. Over time, this is a great way to view your fitness levels increase, and it also helps you see what types of workouts are necessary to strengthen your weaknesses. For instance, if you see your heartrate begin to spike after a certain distance, you know you need to increase your endurance workouts to train that area of fitness.

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 305 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 305 is also compatible with TrainingPeaks.com, an easy-to-use web based training system designed to help athletes train for any event.

Pros

  • Radically new design is better in every way
  • Amazing accuracy and fast satellite acquisition time
  • So simple to set up and use, you will actually use it
Cons
  • No Mac OS compatibility
  • Okay, it's bigger than a sport's watch -- but so much more powerful

I use mine for cycling and running, the direct link to see your workouts mapped on GOOGLE EARTH is FANTASTIC!!!! (the included software is far more stable than the junk Polar included with their HRM's.

Heart rate strap with replaceable battery is coded and comfortable. It's better in my opinion than the Polar products (of which I've owned three)

This is much better than the Forerunner 201 which I previously owned (locks on satellites 10 times faster) and I'd avoid the 405 unless you really want to use this watch as a normal day to day wristwatch (check out the 405 reviews)

One nice feature is being able to customize the display screens. Another review criticized the 305 for the numbers being too small to read while exercising. I don't have an issue but would point out that you can significantly increase the size of the display by simply displaying fewer fields.

My only complaint is that it's easy to leave it on and run the battery down - which is a bummer if you're just about to work out. I wish there was an "auto off" feature which would shut it down if it detects no movement or heart rate within an hour or so. Fortunately, with Li-Ion batteries, as little as a 10 minute charge gives you enough juice for a 90 minute run.

I have owned one of these GPS watches now for 3 years... and it still works like a champ. I travel all over the U.S. with it, and it has always worked for me... It can take about 5 minutes to sync with the satellites, when you are in a new place (hundreds of mile away)... I just go outside and stretch, while it does it's thing. Battery still works good... i can usually use it for 16+ hours, before I ever see a low battery warning. I've even seen the low battery warning while I was on 1.5 hour run, and it didn't run out of juice (30 minutes into run it displayed low battery). the software leaves little to be desired, but all-in-all, I love this thing. My wife is training for a marathon, and asked to use my watch... i use it too much, so I just bought a new one for her.

I really liked my Garmin - for as long as it lasted. I paid $159 in October 2009, so I got 2 years out of it. During that time, I had about 4-5 incidents where the watch apparently just shut off in the middle of a run. Yes, it was fully charged and I could never find a reason for the malfunction. Another problem was that the chest strap was way too big for a petite woman. I would have to use safety pins to keep it in place but even then it wasn't snug enough to register heart rate consistently so I just gave up on it. I would have been better off with the Garmin 205 because of that. However, all that being said, I found it was a wonderful running partner. I loved being able to download all the stats from my run and those numbers kept me motivated to improve time and distance. I would not buy this watch again - from reviews I've read I'm not the only one with the problems I mentioned and it is just way too much money for what you get in return.

After completing my first Half Marathon, I was bitten by the bug and couldn't wait to run another! I knew I needed to up my game and push myself harder to improve my time. I spent a lot of time researching different watches and, based upon reviews, decided that the Garmin 305 was for me. Although other models my have more features, I personally can't imagine wanting anything more. This watch is simple to use, accurate, and doesn't appear to have some of the problems that other models have. I was concerned that it would be too big on my wrist, but because of the shape of it, it's not uncomfortable. I don't wear it for anything but running, but if I planned to, this would not be the model I would get. It's not pretty or streamlined, but it works for me. I would rather have the Garmin 305 than a "cuter" model that is unreliable. The GPS locates sattelites very quickly, in fact, I usually turn it on and stretch a little and its ready to go. Battery life is fine for what I use it for, I have never had it die on me. Long story short, I love it!

As a distance runner, I find that this watch is a great tool for capturing items like distance, time and pace. It is also neat to be able to see a rough map of the run route. That's about it. The rest of the functions are poorly designed, difficult to set up and mostly undocumented. Unless you are a serious geek, you probably won't have the time to figure them out. That's okay. I still use the watch every time I run.
The big disappointment is the heart rate monitor. Mine has never worked properly, and Garmin's tech support is no help at all. As a quick Google search will reveal, this is a widely encountered complaint. If you are looking at buying this product, maybe consider getting the package that doesn't have the heart rate monitor.

I have had my Garmin 305 for about 3 months now, and I can say it is the single best workout peripheral I have ever purchased. I NEVER used to run outside, and now that's all I do. I love the fact that I can see the distance I've traveled, monitor my HR and even check my pace all just by glancing at my wrist. I also love tracking my workouts in Garmin Connect and seeing the super cool graphs and maps of my runs.

A few points to anyone thinking about purchasing:

1. The software that comes with the product is marginal, at best. You must go their Garmin Connect website [...] if you want the cool graphs/maps. The cool thing about Garmin Connect is that you can then share your workouts with others via email, Facebook, etc. You have to connect the 305 via USB (included) to download data, whereas some of the newer models connect wirelessly.

2. I bought the quick release kit as well. You need this if you plan to use the device on your bike as well. . Basically, you remove the rubber straps that the device comes with, but leave the little bars that connect the strap to the watch. Those bars then snap into the bike mount & wrist strap. IMO, the wrist strap that comes with the quick release kit is MUCH more comfortable anyway, especially on long runs where your wrist can get sweaty. As far as the kit, I love it and have used it in 3 triathlons so far this year. Very easy to swap from bike to wrist.

3. The accuracy of the GPS is amazing to me. I will literally run around a big pothole, and then see a little "bump" on the map line when I get home. Also, if I run on one side of my neighborhood road on the way down, and then the other on the way back, I get 2 distinct lines. Awesome!
