Time Your Swim
The swim-proof Forerunner 310XT is waterproof to a depth of 50 meters, so you can wear it in the pool or the lake to time your swim. And its slim design and flexible wristband mean Forerunner is easy to wear in any conditions.
When you're ready to jump out of the water and onto the bike, Forerunner 310XT moves easily from wrist to bike with the optional quick release and bike mounts, making the transition between sports effortless. Forerunner 310XT categorizes multisport activities in one workout and can also log transition time in the process, so you can analyze your performance from start to finish.
Collect Workout Data
Forerunner 310XT tracks your position precisely with GPS satellite data and records distance, pace, heart rate (optional), power data (from ANT+-enabled third-party power meters) and more. High-sensitivity GPS and HotFix satellite prediction mean Forerunner acquires satellites quickly and tracks your movement even near tall buildings or under tree cover. And using innovative ANT+ wireless technology, Forerunner 310XT connects seamlessly to an optional heart rate monitor, foot pod and cadence sensor.
When paired with the optional wireless heart rate monitor, Forerunner 310XT continuously tracks beats per minute and uses heart rate data in advanced calorie computation. Train in a certain heart rate zone to improve fitness and monitor your level of exertion.
Run, Sync, Store and Share
Once you've logged the miles, innovative ANT+ wireless technology automatically transfers data to your computer when Forerunner is in range. No cables, no hookups. The data's just there, ready for you to analyze, categorize and share through our online community, Garmin Connect or our optional Garmin Training Center software. You can even plan workouts on your computer and then send them to your Forerunner.

I wanted a watch that could of course chart maps, distance, speed, pace, approx calories, but also have small features like notification of laps during a run, strong GPS, user friendly software, and allow copious statistics of my workouts so that I can compare my workouts over time (I am an avid runner and biker, and swim about once a week). I found the most packed features in this watch.
COMFORT - the watch seems to be huge initially. I was prepared for this thanks to the fellow reviewer who has posted images of himself wearing the watch. The watch was exactly what I expected after seeing those pictures. That being said, it is comfortable to wear and does not look or feel awkward at all. It has two pins on the rubber strap that lock into the strap, keeping the watch securely in place. Given the heaviness of the watch, there is no need to tie it tight on the wrist. I keep it a notch loose and it stays perfectly in place, doesn't rub against the skin yet is not so tight that it would leave its imprint on my wrist either.
SCREEN - The benefit of the bigger screen is that it can display more information. You can customize up to 4 items to be visible on each screen. This feature was one of the main reasons I bought this watch. I want to see distance, speed, current pace, and average pace. It is very useful now that I have this information available so readily on one screen.
GPS STRENGTH - I switched to this model after having used the Garmin ForeRunner 110 for a year, primarily because I wanted more features which the 310XT had. Compared to the 110, the 310XT's speed of acquiring satellites is remarkably fast. It has probably never taken more than 10-15 seconds, even if I am indoors. The 110 on the other hand almost never picked up signal indoors and took much longer when outdoors. This is very helpful particularly in the winter months when I won't have to stand outside my house in the cold waiting for the watch to acquire satellites.
GPS ACCURACY - Compared to the ForeRunner 110 and my iPhone (with MapMyRun software), this watch is very close in terms of distance, speed, and other such parameters. I know a lot of people want this data to be accurate to a tee, but I've realized that most devices tend to fall within a narrow range and that tiny difference in distance can be due to a number of factors. For example, I typically run a 6.1m route - sometimes I'll see that as 6.08 and sometimes as 6.13. This small a difference in distance can be due to just the side of the road I was running on. Honestly, too small a difference to be of significance.
DURING A WORKOUT - During a bike ride or a run, the watch can be set to give notifications at the end of each lap, you can choose what you want that lap to be, be it 1 mile or 5 miles. The type of notification can also be modified between beeps, vibration, or both. If you have to stop say at a traffic light, the watch automatically pauses recording and resumes within about 2-3 seconds once you resume the activity. You can view Average Pace and Current Pace as one of the many metrics viewable on the watch, in my experience the current pace in reality is your average pace for approximately the last 5-7 seconds so don't let current pace throw you off if it seems too fast or too slow at any point of time.
CADENCE - The watch does not come with a cadence sensor of its own. I had really hoped that this would come with its own metronome and cadence feature, but unfirtunately it doesn't. The 910XT comes with all these fancy accessories, but the cost adds up to around an extra $300! As for the 310XT, it needs to be connected to a bike sensor separately. Yes, this was a significant lacking feature for me, but I have no choice but to wait till one becomes available at a more reasonable price (hope the Garmin folks are reading this!).
ANT - The watch comes a bluetooth dongle (ANT). This can be inserted into the USB hub of your Mac/PC and it will automatically fire up the Garmin ANT Agent software and transfer all data from the 310XT. You can choose which workouts you want to transfer. It also lets you delete data on the watch once you've transferred. You can do this if you want to free up memory space, but after 2 months of heavy use, I still haven't had the need to delete any data. The bluetooth dongle is one of the very few things about the 310XT that I didn't quite like - it is way too tiny and needs to be stored carefully so that it doesn't get lost (black color doesn't really help either). I have kept it in my drawer in the original clear plastic packet that it came in. This packet has a large yellow color sticker on it, so it's easy to find in the drawer. I am still nervous about losing this tiny dongle.
SOFTWARE - The ANT bluetooth dongle transfers data to your Garmin account which can be accessed on the Garmin Connect website. The data is copious and broken down in pretty much every way you could want, particularly if you're a statistics junkie. I was pleasantly surprised at the level of detail this software has compared to MapMyRun (I used to think that was pretty good too, but Garmin's data is better and more detailed). Btw, you can transfer all data from your Garmin Connect account to MapMyRun or MapMyRide accounts as well (you can login to your account there and choose the "Import Workout" option, and then select Garmin from the menu).
PERFORMANCE IN WATER - This was another important feature that steered me to this watch. The watch holds up great under water, I've used this both in open water and in a pool. I agree with other reviewers that the route mapped under water is far from accurate, but I really don't care about the map as much as I do about speed and distance. And on these two parameters, the watch performs great.
BATTERY - I believe the advertised battery life is 20 hours, I haven't had the need to keep the watch on for this long just yet. The longest I have used this at a stretch is 4.5 hours and it worked just fine. One feature that I find strange is that the watch automatically turns on when charging, and stays on. So every time you remove the watch from the charging cable, remember to turn it off if you won't be using it for some time. Strange feature, but just takes getting used to.
CHARGING - The watch has the standard Garmin connectors in their chargers that connect 2-4 points to the watch. The ForeRunner 110 had 4 connecting points which made it difficult to connect. The 310XT has two connectors which are slightly easier to connect. That said, I would still have liked to see a standard Micro-USB or a different type of connector that would have been easier to connect, but I understand the need for a proprietary charging cable that ties us to Garmin's charging cables only.
All in all, the 310XT is a phenomenal watch for triathletes or runners or cyclists looking for all the features that are packed in this device.
They did change with the way the watch fits on your wrist, not for the better. The 305 was shaped to go around the wrist, the 310 just sits on top of the wrist and never feels as solid as the 305 does.
The 305 came with 2 wrist straps, long and short. The 310 just has the short version. I contacted Garmin about getting a longer version and they don't make one for it. So if you have large wrists you are out of luck. I can only get 3 sets of holes past the buckle, meaning that you struggle to get the strap locked in to the sliding catch. If you wear it over your shirt sleeve during cold runs it is barely long enough to fit, let alone get the catch on the strap.
The satellite acquisition is no faster or slower than the 305.
The buttons on the sides of the body are easier to push in then the 305,the only improvement that I have found so far.
I think that I will replace the battery in my 305 and use this as a secondary unit.
For me this is horrible update replacing a better product.
