Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor

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.
Computer 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 computer. Not only does Training Center–which is compatible with both PC and Mac–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 computer 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 computer, 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.

User Ratings and Reviews
5 Stars 3 Years and still Running
First of my Army Friends to have this toy and have been the cause of many to buy this product. Simply an awesome tool while running to give you exercise time, distance, pace, heart rate, and much more. Awesome tool after running as it automatically creates a log for every run while it is on your wrist calculating time, distance, and splits(I set mine at 1 mile pace splits). Every friend I have loaned it to has bought their own soon afterwards. Over the past 3 years it has been very durable with no issues. My only complaint is the software that it comes with has really baseline maps with no graphics(I know Gramin can do better in this area), the pace lags about 5 seconds behind but is still a good benchmark to see where you are at that point in time.
5 Stars Love this thing
I recently decided to start running again, and was quite curious about the course i was running which seemed tough. In particular, I’m training in the hills and wanted to know how far I’m running and the elevation changes. This watch is really great for that. I know can see my heart rate, how it is impacted by grade, and how far up and down i’m going. I can see that my heart rate jumps as I hit 25% grades, and my pace slows to a crawl. But I feel much less guilty about it…
I was worried that this watch would be enormous on me. I have a very small wrist, at 15cm, and most watches are too big. I also hate clunky things. Although this watch is definitely much larger than i would wear normally, it is actually reasonably comfortable and does not bother me or awkwardly hit wrist bones, so i was pleased about that.
I’ve become quite addicted to running with it, because for one thing it removes fear of unknown courses. I always have a good idea how far I’ve traveled, so I don’t worry so much about going out too far.
I also like seeing progress, since with the software I can see how I’m doing if I repeat a course, whether my heart rate or pace are dropping and so forth. And, when running, I like being able to check on my pace and distance so i can judge them better.
The software that comes with it is so so. Maybe it has some great features but they aren’t immediately intuitive, but the online software on motionbased is really cool. I like being able to share my courses with friends and see a map of where i’ve gone and track progress.
On vista64 it will complain a bunch when you install the drivers, but it eventually figures things out and works.
I’m sure the watch has a million features I haven’t touched yet. I’m just using it with the simplest set up, but so far I really like the thing, and it definitely helps inspire me to keep training.
5 Stars Keeping me on target
An excellent device for marathon training.
I am running my first marathon in October and in a sort of weird way, this device is key to keeping me on target. I use it for the entire week, against my set training plan (32 miles this week) without charging it. At the end of the week, I pop it in the dock to download data and recharge.
I use it primarily to track my mileage, time, and pace. I also look at heart rate and elevation to determine improvement. The real beauty of this device is the ability to run ANY route you want, without even thinking about the distance before hand.
The garmin Training Center software is so-so. I would really like to do more with the data in terms of analysis and graphing, but it’s a pain with the raw data (export function). I understand you can use the web software (MotionBased or Connect) to do more, but I have not experimented yet with the web software.
As for size, some have complained about it, BUT I do not have any problems with the size. I do not have big wrists either. It is certainly larger than a watch and it does take up a good portion of the top and side of the wrist. Look at it this way, you look like a serious runner with it! It *may* be a problem for a petite female with very small wrists. The heart monitor is also no big deal. I wear it all the time, and barely know it’s there. Sometimes when I sweat a lot, it starts to slip down a little. You can either tighten it or occasionally re-adjust as you run. I don’t like it tight, to ease my breathing.
As for reliability … NO issues. Works flawlessly. It does take a couple of minutes to acquire satellite signal prior to run.
I am glad I did not buy the newer 405 based on its reviews. (But the new 310XT looks very nice)
In my opinion, you can’t go wrong with the 305.
5 Stars Great tool
Gps works great. Plenty of info to review to make adjustments to your training program.
5 Stars keeps me honest
This is my second garmin and I love it. I am a walker and every saturday I do 12+ miles….with my garmin I can’t cheat and cut my walk short and have to be honest about how many extra calories I can indulge in on saturday night! They are accurate and rarely don’t work just as they are supposed to.
