I have had my Forerunner 305 for almost 3 weeks now. Previous to this I used a Polar S150 (wired bike mount) for several years and a entry level Polar before that, so I am used to basic heart rate monitor but not advance data recording or GPS.
I have tested the Forerunner 305 running, biking and swimming and have been generally very impressed.
General: The concept of acquiring satellites before I get going took a little getting used to. After the first couple of times I generally get satellite acquisition within about 30 seconds as long as I am outside or in my enclosed front porch. I set the unit down so that it is completely stationary while acquiring satellites. I get spotty to no reception indoors. The heart rate monitor functions well in comparison to my Polars. I have only had erratic heart readings at the end of one bike ride (fixed by adjusting the strap), which is better performance than I generally would get with the Polars (Except for Swimming, see below). The grade measurements are so erratic as to be totally useless. I have had the grade measurement vary from 8% to 25% back down to 5% within one minute of sustained climbing on the bike. I believe this is due to a poor averaging algorithm (2 point average as opposed to smoother averages involving more points). This is something I intended to test once I figure out how to access the raw data. Data recording is interesting, but is highly dependent on the software used to analyze it. Training center software is decent but unsophisticated (lack of user configurable option is disappointing in a $300+ product). Motion Based has been fun to use, especially the map player. As noted in a previous post of mine errors in distance calculations arise due to Motion Based insistence on connecting erratic track points recorded when you are standing still.
Running: To this point I have done about half a dozen runs of 3-3.5 miles each on a couple of different courses. Mostly I run on trails with trees (no real leaves as of yet) with some street and open field running mixed in. Generally in the trees I average an accuracy of about 25 ft, which I consider to be pretty good. The tracks and distances are both reproducible to within this approximate 25 ft range. I have found the "instantaneous" pace to be somewhat erratic but generally within approximately 5% of the short term mean. The auto stop feature (I have it set to stop if pace falls below 30 min mile) working decently on the run but occasionally does not register that I am stopped. Overall I am very excited to easily track my running distance and have a pretty good idea of my pace.
Biking: Used for approximately 10 bike rides both on and off road. Despite some concerns that the antenna faces the wrong way when mounted on the handlebars (I mount mine by wrapping the monitor around a piece of foam) I generally get great GPS reception on the bike. Accuracy is generally about 15 ft on open road and 25-30 ft.on trails. The speed and distance seems to be very accurate and the precision (reproducibility) is within 1%. The auto stop feature works extremely well on the bike, starting and stopping the unit within 1 second. The one down side is that the buttons you are most likely to use for cycling are on the side of the unit (the up/down and occasionally the mode button).
Swimming: I have only tested in an indoor swimming pool, hoping to be able to record my heart rate. Unfortunately, unlike my Polar S150 the heart rate signal cannot be measured in the water. I did these tests with the receiver under my swim cap, which was pretty comfortable and I could access the buttons easily. There may be more utility for swimming in open water.

I upgraded from my old timex to a 301 unit. Then to the 305. I run with 4 other marathoners who use the 301. Overall they are pleased with the units. This weekend I ran a marathon up in Ogden, UT. At mile 21 my unit froze up and never regained signal. Even after finishing the race. I upgraded to the most recent software using the garmin web update prior to the race & full charged unit. Here is my experience of the G305.
(Unit fully charged before long runs)
Pros
-Consistent heart rate over the 301 unit
-No elevation spikes like the 301 unit
-Motion Based software works great
Cons
-Signal dropped on three long runs different locations
Note: Other runners w/ 301 did not drop signal
-Takes a long time to get signal
-Unconfortable compared to 301 unit on wrist
After the unit freezing up during a marathon I'm going to return it and buy the G301 again for $200 less than the G305. In my opinion the signal does not work better than older garmin units. When my unit drops signal my friends w/ the 301 just laugh and say how much did you pay for the unit... Do you homework before paying $350 for this unit.
Good luck!

I think Garmin has made improvments since this unit first came out. I've had my third unit for a couple of years now and updated the firmware. The unit has not locked during long runs or several marathons in the canyons or downtown in cities. The price has also dropped significantly. I would recommend at the lower price. Happy running.

I bought this product with some trepidation, after reading the mixed reviews on Amazon.com, so I made sure that my supplier had a good return policy. However, I have to say that it is an amazing piece of equipment, and kudos to the people that developed it. Sure it has some kinks that I am prepared to put up with, bearing in mind that this technology is in its infancy (especially at this size). I am training for my first marathon and I have found the forerunner to be great for logging and keeping track of my runs and my overall progress. Sure the real-time pace is not hugely accurate, but I feel very confident that it keeps very good track of my distances and overall pace for each of my runs (if I do an out-and-back run, the plotted course and calculated distances are very close). As I do most of my weekday running in boring suburban DC neighborhoods, it is liberating that I don't have to do the same measured route every time to keep track of my pace. I can wander at will, and head towards home when I am getting close to my desired number of miles. The virtual running partner is a great motivator. How else can you get a running partner to start the run at the same time and place as you and to run at a constant pre-set pace? It was a little annoying when I was ahead of him/her and needed to wait to cross the road; meanwhile I watched him/her passing me out!! I tried the auto-stop function for the first time this weekend, it worked ok, but did have some kinks...maybe it was because of very heavy rain and lightening we were having. The heart rate monitor seems to work fine. I have found signal strength to be no problem (I live in DC area, not sure it that makes any difference). My neighborhood has plenty of trees and the parks that I run in are heavily forested (its summer here). As I drove into the park this weekend during the storm my satellite radio kept losing signal under the (very wet) tree cover, but the forerunner seemed to work fine (except for the autostop). I wish their maps were more detailed, they just have the major streets, I guess Garmin chose to provide a stripped down version.....they should have done a better job there. Overall, as a technophile, I love this piece of equipment, and look forward to seeing how they improve it in the future. You do need to understand the limitations of this device though (e.g. somewhat accurate real-time pace information, undercounting overly twisty routes). I guess I am lucky that I have had no problems with it so far (it has only been a month), but I will update this if I need to call their customer service.
Has changed the way I run March 6, 2007

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.
 Great - when it actually works, HORRIBLE customer support June 9, 2006

I got my first Garmin 305 about 2 months ago. The first day I got it the Enter button stopped working. I returned the Garmin 305 to the dealer and was quickly shipped a new one. I am currently using the second Garmin, however the heart rate monitor function on the watch stopped working about 2 weeks ago. I contacted customer support and they said they would ship me a new one, however they only shipped a new chest monitor instead of the watch. Needless to say I still have the problem. Calling customer service is EXTREMELY painful. The wait time is 30-35 minutes just to talk to someone. I have tried to call morning and afternoons and it does not change the wait time. (I am actually on hold right now as I type and am going on 25 minutes.) I should have known not to give my old Polar to my wife.
The 305 functionality, when it works, is very cool. Mine locks in on satellites within 1-2 minutes and does a good job measuring average pace per lap. I love the auto lap function which I have set at 1 mile. The instant pace is off due to the delay in tracking with the satellites. It is actually showing my pace delayed about 10-15 seconds. I have gone to just using the average lap pace and it gives me what I really need to know. The only problem I have besides the heart rate not working at all, is the distance tracking on one particular trail I run. The trail has a lot of tight switchbacks and the area is covered with trees. The distance registers about 1.5 miles short on a 12 mile loop. It does work well everywhere else I run.
New update: I finally got through to customer support and they are making me send my watch in for service. Maybe I'll enjoy just running with no data for a while, yeah right!
