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.

Transition Effortlessly
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.

5.0 out of 5 stars 310XT is most everything Garmin says it is, September 6, 2009

By 

David Rosenfeld "Dayrems" (San Rafael, CA USA) - See all my reviews

This review is from: Garmin Forerunner 310XT Waterproof Running GPS With USB ANT Stick and Heart Rate Monitor (Electronics)

I felt compelled to write a review, because I am disturbed with what some other reviewers are publishing. This is the best watch of it's kind I have owned, and as long as a purchaser understands what it does, and it's limitations, I think they will be more than satisfied. It may be that this watch will not meet their needs, but it should not be a cause to deliver a poor rating.
I have owned the Forerunner 305, the 201, the Timex GPS and a Polar, so I have years of experience. Since I do triathlons, I was most looking forward to the waterproof controls, and 20 hour battery. The charger is a bit funky design, but for me it seems to work just fine. My battery has been lasting at least 16 hours--I haven't tested it further before recharging. One issue that I had with the 305 also, though: the watch should be TURNED OFF while you are charging. If not, as soon as you disconnect the charger, since the watch is ON, it will start "discharging" (as it does normally while it is on. I have been caught several times with a depleted battery on my 305 because of this quirk--I think the watches should be programmed to automatically turn themselves off when the charger is connected).
I have used the new watch swimming, biking and running and hiking, and I am pleased with the performance for each sport. One reviewer pointed out that there should be a "swim" mode--I agree, but I think Garmin may have avoided that mode because the GPS does not work well in the water. Several reviewers complained about that, however Garmin does write on their website AND in their manual that the GPS does not work well in the water (I don't know that I would blame that on Garmin--probably the technology is just not there yet--besides, GPS signals do not penetrate water.) In fact, I did NOT get an accurate GPS distance reading for open water swimming, but it did map my COURSE correctly, albeit with a lot of zig-zags (I know I can't swim in a straight line, but I am not THAT bad).
The biking portion works great. The Garmin matches pretty closely with the distance measured on my bike computer (I don't have the Garmin bike sensor--I want that and the quick-release mount for my next birthday). Of course it also tracks speed, altitude, heart rate, etc. (I used the heart monitor strap from my 305).
Running works well also, basically same as biking although I do set up the display screens differently.
Other, useful new features I have noticed:
1. The watch locks onto satellites more quickly than my 305
2. The watch vibrates, although I wonder how this affects battery life. For instance it vibrates every lap (if I set it) so I know I have completed an autolap without having to look at the watch.
3. The software is more refined (lots of small fixes. For instance the settings function lets me know what sport mode I am in--although I think this could still be made easier and less confusing. And the time zone can be put on automatic--I always wondered why they couldn't do this before--the watch knows where it is for gosh sakes. And there are extra custom screens if you want them--statistic hounds take note.)
4. Wireless data upload. Very nice! Their new "Garmin Connect" site is also pretty useful, and the data can be uploaded directly to the Internet.
5. The 310XT is not much smaller or lighter than the 305 (according to the specs), but it FEELS MUCH smaller and lighter.
6. There is a progress bar for the battery charging. I would like to be able to see how much time is LEFT in my battery--I wish Garmin would add this.

In summary, I think this is far and away the best GPS watch Garmin has made, and is especially appropriate for triathletes (despite the swimming issue). You DO need to become accustomed to using the watch. Although I do not think it is hard to use, you SHOULD read the manual. At least you do not have to keep RE-reading the manual like I do for some other gadgets. I do think this watch is way overpriced, but I am a gadget freak, and I'm sure the price will come down over time, like it did for the 305 (which is a great deal, now, btw, if you don't need a 20 hour battery-life and a waterproof stopwatch :)

3.0 out of 5 stars Somewhat Misleading Advertising to Triathletes, August 28, 2009

By 

graymoment (Orange County, CA) - See all my reviews

This review is from: Garmin Forerunner 310XT Waterproof Running GPS With USB ANT Stick and Heart Rate Monitor (Electronics)

This device has been represented as a triathlete's watch and the first swim proof GPS watch. If you watch the video from Garmin or see any of the advertisements, Garmin leads you to believe that this watch will collect reliable data for all 3 multisport events. It is reasonable for someone to assume this watch can be worn in a race and collect GPS data in the water, since, of course, SWIMMING is the first event in a triathlon.

If you are considering buying this watch realize the following:

-This device does not collect usable data in the water, period (other than time, which any $20 waterproof watch can collect in a much smaller form factor). No heart rate data and totally unusable and inaccurate GPS data while in the water.

-There are preset modes for run, bike, and "other", in which "other" shows a person on skis (explain that one?). They intentionally omit a category for swimming, despite advertising that this watch is for triathletes (see the photo I added under product photos).

-You will need to purchase a separate quick release kit if you want to use this watch on a bike. It does not get accurate data on a bike if you are wearing in on your wrist. It auto pauses, then unpauses for most of the time I am riding if I wear it on my wrist -- even if I have it set to only auto pause when completely stopped. The quick release kit IS NOT the more common one for the 205 and 305 Garmin 010-10889-00 Forerunner 305/205 Quick Release Kit, so do not buy that one. They have made a new one for this watch and most places do not have it in stock yet. As of the date I am writing this review, it is not yet available on Amazon.com. Go to Garmin's website and look under the accessories tab for this watch. You will see a different model number. I have confirmed this with customer service. The part number for the proper quick release kit is: 010-11215-00. Google it.

-If you want foot cadence or the ability to track distance indoors and assume you get it for spending $400 on this device, think again. You will have to buy a separate foot pod which costs $80-100, depending on where you buy it (earlier Garmin Forerunner watch kits included foot pods). Garmin Foot Pod SDM4 (ANT+)

-The watch is large and sits high on top of the wrist (they packed 20 hours of batter life into this watch), so to wear it under your wetsuit will let water in the wetsuit, or you will have to wear it on top of (or crammed in front of) the wetsuit, which will not allow you to remove your wetsuit without first removing the watch (thus adding time to your transition and sort of negating that whole "triathlete" angle). You can see a photo of this watch on my wrist under the photos section of the product.

-There is no way to turn off GPS tracking for only one of the 3 events in multisport mode. Therefore you will always either have incorrect GPS data recording for the swimming mode (or, actually "other", since there is no "swim" mode, as previously mentioned). I have called customer support and they confirm this. Their solution was to turn off GPS while I am swimming, then reset and manually start a new timer and mode during transition 1 for my bike event. I'll let you be the judge of how to take that advice.

So, in conclusion, if you want to setup this watch for a bike and run, and want the ability to wear the watch in the water before hand (and no start it unless you want some incorrect distance data included), you will need to buy:

$400 - the Garmin 310XT with HR
$25 - quick release mount kit (for wrist and bike) (no link in Amazon yet)
$80-100 - foot pod (if you want cadence)
Garmin Foot Pod SDM4 (ANT+)
$35-50 - speed/cadence sensor (if you want cadence for the bike)
GARMIN 010-10644-00 Speed/Cadence Sensor

You'll be into it for $575 retail. Garmin, you did us wrong on this one. Some of us are willing to spend this kind of money on a product if it proves to do what it advertises itself to do. We're not asking it to do anything more than perform as advertised. I realize your fine print saves you from lawsuits, but it doesn't gain you repeat customers. It sends them over to Polar.

[EDIT: I have edited the title of this review to what it currently reads from "Misleading: Not a Triathlete's Watch," because it seems that Garmin has somewhat softened their advertising and marketing surrounding this watch. I purchased this watch when it first came out in 2009, and at the time the marketing videos and advertising in triathlon magazines mentioned nothing about the fact that it doesn't track GPS data in the water, and in fact seemed to lead the consumer into believe it does. That advertising has since softened.]

4.0 out of 5 stars Decent watch, but a lot of catches, August 21, 2009

By 

Josh McCarthy "endurance junkie" (Alexandria, VA) - See all my reviews
(REAL NAME)   

This review is from: Garmin Forerunner 310XT Waterproof Running GPS with USB ANT Stick (Electronics)

The 310xt was my first Garmin purchase. After years of having family use the Edge and the Forerunner for biking/running I decided I'd take the plunge when they came out with "the triathlete's indispensable training tool" in the 310xt.

My first thought was this was pricey. But, looking at the ForeRunner 305 & 405, I realized it wasn't that much more expensive for the additional supposed features and the "newness". Then I looked at the price here on Amazon and almost passed out. $550? Without the HRM strap? Ouch. If you're really into this watch, don't buy at that price. Search for the ones priced at $399. Most sites sell at that price.

Ok, onto the feature set. Large, clear buttons. Large screen. Ability to track multiple sports. Quick upload of data. Lots of customizable options and screens.

Pros:

Easy to set up and use. Pairing with the ANT USB stick is simple and can quickly get you started without the manual.
Online tools are pretty good (much better than previous iterations). Also, works with the MapMy list of sites (fitness, run, walk, hike, bike, swim, tri).
Customizable display allows for up to 4 tracking items per screen. So, you can track pace, HR, time and distance covered on one screen then scroll to another and get a map of your HR, your calories burned and a bunch of other potential options, all determined by you.
You can create routes on your watch and when you run it, it will record whenever you are on that route path. Great for comparing against previous training routes and for quickly setting the route and having it track you properly. Once you are on the route, it tracks you.
Auto-multisport option allows you to set that and when you click lap, it will dump you to the next "sport" whether it be a transition or another sport such as biking/running.
Tracks you the individual after you enter your height, weight, level of fitness. Provides caloric burn and other related info based on your input.
Virtual training partner. You can actually have it show how you're doing on a saved route versus your virtual training partner. This partner is a previous version of you doing the same route and tells your pace and how far you're up/behind. Pretty cool.
Multitude of things you can configure and display/adjust/fine tune.

Cons:

Swim? As I quoted from the Garmin site above, this watch bills itself as the triathlete's indispensable training tool. Umm.. triathlete means 3 sports, typically involving SWIMMING, biking and running. Swim is not an option. In fact, when I clicked other one time, it had what appeared to be an icon of a downhill skier. I'm not sure how that showed up since that option isn't there. HUGE mistake in my book for a watch billed to be for triathletes.

Elevation Accuracy? This one is WAAAAAY off. On a 3.3 mile run, it had me ascending 853 feet. Unless I'm climbing the Washington Monument, I'm not getting that type of elevation in 3.3 miles. I'd have to say it is off by, 600 feet or so. On a 60 mile bike ride, it had me at 1500 feet and that one at least took me up some legitimate hills.

Switching events: There is no way to switch events mid-stream on the watch if you didn't set it properly to begin. Let's say you ran one day and then biked the following day. If you left it on run then switched when you realized the mistake, it clears the data and you start with a new workout. The original workout is kept but you can't append the "new" workout on either on the watch or with any of their software (both installed SW and online site). So, when workouts are categorized, it shows a multisport recording on the installable software and whatever you mistakenly set in the online site. You then have 2 workouts you can't consolidate or run reports against without manual intervention.

Swim accuracy leaves a bit to be desired. While I haven't put it through its paces and will hopefully edit this review in the future, for a 1/2 mile swim, this thing was way off. Beach, opposite direction, gaps. All were part of that swim result.


While there are a lot of pros (which do warrant a 4 star), the cons are extremely negative. Since I don't have a watch to keep track of everything, this one will have to do. At such a price point, I'm highly disappointed in the overall performance considering it is billed as the triathlete's dream. It really does track mileage well and with enough fudging (using the elevation in MapMyRide instead of from the watch) and by manually adjusting routes in my various tracking sites, I can get close what I want. The HRM is good and the coupled effect of it all makes it as worthwhile as having a set of watches out there. But, I will not be ultimately promoting this to other athletes. While I've managed to make it work to a 4-star rating with my own fiddling, I wouldn't recommend it to a hardcore triathlete. Being my first training watch for my first Ironman, I wish I could say there were other watches which had the functionality I needed. Unfortunately, I'd have to wear two or more plus a bike computer. Even more unfortunate, in order to get what this watch said it can do all in one I might still need another to keep this one honest.
