Invaluable information
have been using the watch for 3 months now and the way you can break down the data is great. you can tell at which speeds, grades, cadence, etc, etc that you are struggling at. Great device. I only wish I could wear it swimming.
Forerunner 305
Overall, this has been an extremely useful tool in helping me to greatly improve my fitness. It is nice to have this GPS unit all in one package, rather than having a separate GPS "pod". I would (and have) recommend this product.
Garmin Forerunner 305
I have mixed feelings about my forerunner 305. When it works, which is about 95% of the time, I love it. It gives terrific information (with very little useless bling) and is customizable. PC interface is straightforward and very helpful. But... there have been problems. I've had mine for over 2 years and note that it can take up to 30 minutes to lock on satellites (clear day, open field); worse, the battery sometimes drains itself overnight, leaving you with nada when you need it (happened to me the morning of a 1/2 IM... arg!). Mine is an early edition, and I've heard Garmin has made improvements; iron out the bugs and this is a terrific training tool.
Really like the forerunner
I really am happy with this unit. It is very easy to use, provides very good data and feedback and is great to design training runs etc to really help me stay on target. The display is also really great, and its been engineered really well - many small details were designed in. The troubles/cons I mention below are far outweighed by how great this unit is to actually use.
I also got the bike mount kit, which is superb, and I bought the wireless cadence and speed sensor so it goes from biking to running and visa versa really well.
Only drawbacks that trouble me: 1.) the data can vary a bit due to satellite drift, and also calories are based on distance traveled, and seem a bit high. 2.) it doesn't capture all my data well, for example, if I do an indoor run/ride, the Calories won't work 3.) The software seems to lump multisports workouts together so that I can't analyze the individual legs against solo sport workouts.
