 Excellent workout toolMay 04, 2006
By PAZMAN
I like this thing quite a lot. I've had it for about three weeks, and have used it on 12 workouts so far. I use it primarily for running, with biking a secondary usage. The main reason I wanted it was for the instantaneous readout of distance, running pace and heart rate, the latter needed for the speed work I want to do this running season.
The core functionality (distance and heart rate monitoring) works perfectly. There's none of the signal drops I've had with other heart monitors. Once the satellites are initially acquired, I've only had one dropout when I was outside. The initial acquisition of the satellites can be quirky and can take some time. The accuracy (according to the readout) is +/- 25ft, depending on how many satellites can be found. I've compared the distance measurement on the GPS with a known, measured distance on one of the trails I run on (the Chicago lakefront path). The GPS always increments a mile when I'm within 5 or 10 feet of the mile marker sign on the path. Well, I guess that's the least I should expect from a $350 GPS unit! Of course it's bigger than a normal running stopwatch, but that hasn't bothered me at all. The heart rate strap is also very comfortable and well-designed.
The display is crisp and has one outstanding feature: The information presented on the various pages can be completely user-customized. The default screen layout is rather poor, but in just a few steps I could replace it with the information I wanted to see while I run. There are almost 40 different data fields you can choose from for display. Examples: current pace, average lap pace, average run pace, heartrate, distance.
The only disappointment is the point-in-time (instantaneous) pace measurement: It varies wildly during a run. I see swings as big as +/- 3 minutes/mile. I'm a marathoner and I know my pace is fairly consistent during a run. I just looked at my run today, and according to the data the first mile varied from 5:57/mile to 12:06 mile. I suspect the problem is either in the averaging algorithm (too short a distance?), or in the uncertainty that results from different satellites coming in and out of view. The variations seem to get worse under tree cover compared with an open area. Luckily there's a lap-average pace that can be presented, and at least that value is useful and more accurate. The bottom line is that you can't look at the watch and say "right now I'm running 9 mins/mile". There is the ability to specify a pace smoothing factor, but I have it maxed out and still see the variations. The elevation readout also seems inaccurate, but that isn't important to me.
Upload of workout data to the PC software (Training Center) is transparent. The PC software is very good for presenting time/distance/pace/heartrate/calorie data. However the maps it shows are very crude. I've worked a bit with one of the online, subscription services (MotionBased). That looks really good and provides some additional functionality beyond the included Training Center software, although I still haven't decided if it's worth the $$$ yet for long-term data storage. MotionBased allows export to Google Earth, and it's tremendously cool to see your running path superimposed on a satellite image. You can recharge the unit through the USB port on your computer, although it's slower than using the dedicated recharger.
I had hoped that owning this device would prove motivational for me, and indeed it has. I can't imagine running or biking without it. Updating my training log is trivial now: Plug this thing into my computer, and it's done. My hope is that a future software update will do something about the pace calculation (maybe a few additional levels of smoothing?). If so, the Forerunner 305 would earn 5 stars+++.
Positives:
Flawless heart rate sampling
Great distance measuring and lap-average pace calculation
Seamless integration with a PC
Fully-automatic training log update
User-customizable display
Negatives;
Wildly-varying pace readout.

 Better than 405 & Polar...GOOGLE EARTH alone is worth the upgrade!!!May 27, 2009
By Y. R. Wu
"The will to win is nothing without the will to prepare - Juma Ikangaa"
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.

All I hoped for!Aug 29, 2006
By M. Leuzinger
With a few one-star reviews, I was a bit hesitant to order this. Now, after two weeks of use (10 runs of 2 to 2.5 miles each), I have no regrets with the purchase whatsoever.
I haven't had any of the problems reported by any of the one-star reviewers. It syncs to the satellite in a reasonable* amount of time, seems to track my pace very well, tracks distance well, and the heart rate monitor seems WAY more accurate than the dedicated exercise machines at my local gym.
*by reasonable, it does take a minute or two to sync to the satellites each time. That's the only thing I could possibly think of improving, but it's not a big deal. Being the super-impatient person I am, I often turn on the watch, set it on my front porch, go back in and change into my running outfit, and by the time I come back out it's ready to go.
I haven't seen the pacing issues others have reported. I'm a beginning runner... but if I keep a solid pace... it reports about 10mins/mile... if I push a little harder... about 9mins/mile... if I let up... about 11mins/mile. It seems very consistent over my entire 2-2.5 mile run.
I have a 2.1 mile run where I've done the same exact route about 6 times... and when I compare the maps of each run... they overlap almost exactly.
I have thyroid and heart issues, and this watch gives me the confidence to know I'm not exceeding my max hr for too long (I can easily get into the 180's) and gives me the feedback and stats to keep me motivated.
Last but not least, I've bought dozens and dozens of items from Amazon over the years, and this is the first review I've taken the time to write - hope that gives you an indication of how happy I am with this product. ;-)

Has changed the way I runMar 06, 2007
By P. Lange
I have had the 305 for about 6 weeks and am very pleased with it. It is my first GPS watch and has exceeded my expectations. I had read the concerns with the altimeter and agree, it does not provide useful or accurate information so no surprises there. The real issue for me was how well it would measure distance. I have found it to be very accurate and reliable. I have several runs that I have clocked with the car and measuring tools on Google Earth; the Garmin hit my mile split expectations anywhere from spot on to 20-30 feet from what I believed the true splits to be. At the end of the 10 mile run I was also within 20 feet of expectation. So maybe one mile measures a few feet long, another a few feet short, but cumulatively it was right on my prior expectations.
The heart rate monitor does jump around a bit on pulse rate but once I settle into a run it seems more reliable and is certainly useful. I have found that if I put the chest strap on a few minutes before running I don't get the wild initial readings when I start running.
As to my headline that it has changed the way I run, because the distance measurements are so accurate the Forerunner has freed me from the old measured courses I have run for years. Instead I just take off wherever I feel like going with complete comfort as to splits, pace and distance (and yes, I am one of those who really cares whether I ran 5.00 versus 5.25 miles when calculating my pace). I set the watch to ring at each mile so I can simply glance down and figure my pace. It is also great when traveling as you can run any distance accurately without any planning effort.
I also enjoy downloading data to Sporttracks (third party free software) to see my runs overlayed on a map. Often it maps so accurately it will clearly show which side of the street I ran on and where I crossed from one side to the other. Running has never stopped being fun, but the freedom this device has afforded me has added a new element of enjoyment.

An ImprovementApr 19, 2006
By Jennifer
"ER Doc"
This is a definite improvement over the 301. I had several complaints with the 301:
(1) The heart rate monitor did not track well, and would often jump up to 240, which was a problem when looking at average heart rate later;
(2) The tracking was bad sometimes in the woods, where I run (it could vary half a mile on a four-mile course, and even worse, the elevation could spike 1,200 feet at times and completely change the profile of the run);
(3) The unit was not ergonomic, the buttons were difficult to push, and the screen was hard to see; and
(4) It took forever to acquire the satellites.
The heart rate monitor comes with a new sensor that is more flexible, comfortable, and offers more reliable data. The tracking is much better and more consistent. The unit is much more like a watch, the display is great, and the buttons are much easier to push while on the go. However, it still takes a while to acquire the satellite signal. It is a bit improved, and is not dissimilar from other Garmin products, so I'd have to say that it's OK.
The BIGGEST improvement is that this model is more like a typical GPS in that it offers many different modes and screens to track various types of information (one can toggle between three different screens). For example, on one screen, I have the current time, sunrise, sunset, and running time. On another screen I have the grade, altitude, average pace, and current pace. On yet another screen I have heart rate, calories, distance traveled, and heading. It is totally cool.
I use this thing for running, biking, rollerblading, mountaineering, skiing, and just about everything else outside. I am really happy that I spent the money for the upgraded version.
