Summary: Purchased six weeks ago with the heart rate monitor and still trying to get used to the features. Did a half marathon with it two weeks after purchase and the stats came in handy as I have never had a watch with all these features, especially the heart rate and being able to see the changes in pace during the rate. Going to start training for anohter half marathon in January, so looking forward to using the features. Will try to update my review by then.
Summary: The watch is a nice replacement for the Garmin 305 that I used for 5 years. Works just as good as the 305, a lot longer battery life in the 310. The new communication mechanism (ant) is half baked. I had years of info from the 305 in training center, but the software upgrade path flat out didn't work. After backing up my workouts, re-installing windows and the new ant software, it still failed. You have to create an online account before the software will work right.
Summary: It's just as good - and bad - as the original. Why on earth garmin won't come out with a cloth band that fits this watch, I don't understand. Other watches they make have them, why punish the owners of this watch with these uncomfortable plastic bands? Was surprised to see the "kit" arrive in a little tiny ziploc bag, rather than the ubiquitous, obnoxious, excessive clam shell that everything seems to be packaged in today.
Summary: Loved the GPS. I live in Guatemala (Central America) and de GPS Works perfectly, however the watch doesn't show the heart rate monitor in the screen when your running. The only thing you can do is configure alarms, so when your heart rate goes above 87% you will know. The watch vibrates so you know when an alarm goes off. It has alarms for everything, which is great.
Good watch, though slightly overcalculates distance

Summary: It is a great training watch for running or biking, though after running it for a few half marathons, the distance is a little off actual distance, but not by as much as the iphone apps, so still a great option for training.
Summary: I have many years of experience with sport/fitness watches. As a marathon runner, the 310 is the best device of its kind for the money. It has everything a long distance runner uses or needs. It has been steadfast reliable over 2 years in all kinds of weather and conditions. The only weak link seems to be in the chest strap, it goes kaput about every 8 months. I'm currently on my 3rd, but garmin has replaced each with just the minimal questions.
Summary: I bought this because I had a 205 for about 8 years that was getting finicky; i.e., sometimes couldn't locate satellites when turning on. Thought I'd upgrade, but this one is having a hard time under trees, which is mostly where I'm running. Once in a while it will auto pause when I'm still moving. I think I read that the gps is in the face of the watch whereas the 205 gps is under the face where it meets the band.
