The 205 watch is sometimes even cheaper if really right for you can find one.(Click for a larger version.)]] =What to look Look forin a Running Watch=There are several A modern running watch often has a huge number of features , but I think it's best to consider when looking for a runners watchfocus on its ability to answer these basic questions. * GPS provides an easy measure of how '''How far youdid I run?'''ve run, which This is critical probably the key feature that most runners are looking for , and it requires good [[GPS Accuracy]]. How much the accuracy of a watch will impact your trainingrunning will depend on the course. Overall, most watches do pretty well in straight lines, but suffer when things get twisty. While it My testing is possible to map out a run afterwardstough challenge for GPS, this tends to be tedious so it highlights the differences between the great and the appalling. With the advent of the [[Stryd]] footpod that's far more accurate than GPS and doesn't require any calibration, Stryd support is typically less accurate now more important than GPSaccuracy. ** '''How fast am I running?''' While you can work out your average pace from your distance and time, you'll often want to know how fast you're currently running. Unfortunately, GPS is easy to rather poor at answering this question, so you need a [[Stryd]] footpod, or use [[Pace From A Footpod]] and a first-generation [[Footpod]]. An accurate enough indication of your current pace is important for most any training program that requires runningat a specific pace, but it is not accurate enough and for things like interval trainingsuccess in racing at many distances. ** The errors in '''Where am I?''' It's not unreasonable to expect a GPS average out over enabled watch to tell you where you are or how to get back to the start. Navigation varies from a simple compass needle showing the direction to return to the start to a display of the route you've just run, but they cause or a problem when trying to display current pacepreloaded course. * '''What's my cadence? '''A footpod can be used display of [[Cadence]] is a critical training tool and newer watches are able to use an internal accelerometer to provide Cadence without any accessories. Other watches may need a [[CadenceFootpod]] and in some or the newer Garmin watches it can also provide pace use the running dynamics heart rate strap. A Cadence alert will help you stay in the right cadence range, and distanceis a useful feature. Unlike GPSThere are several additional features to you could consider, footpods need though I'd argue none are as important as the above questions. * '''Weight.''' None of these devices weigh enough to have a noticeable impact on running performance, but the weight can be calibrated to provide accurate pace/distancenoticeable. * A barometer will measure '''Size.''' The size of these devices varies widely, and the larger devices can feel a little bulky, especially if you have a smaller wrist. I've provided the size as the atmospheric pressure and volume in cubic centimeters to give a single number to compare. * '''Waterproofing.''' Even if you altitude. This don't swim, having good waterproofing is more accurate than GPS, but will require calibration important to adjust for weather related pressure changesprevent your watch being destroyed by the rain or sweat. * '''[[Heart Rate Monitor]].''' [[Heart Rate]] is important information when training, though it is important to understand the limitations of heart rate based training. Having a [[Heart Rate Monitor]] that will record your heart rate is particularly valuable for evaluating your training. The heart rate ** [[Optical Heart Rate Monitoring]] is more convenient, but does not work very well. ** While the chest strap that goes across your chest based monitoring is remarkably reliable, you can be intrusive have problems with chaffing and sometimes can chafe. Polar heart rate monitoring is far better than the Garmin equivalentpoor reception in some situations, but there are [[Fixing Heart Rate Monitor Problems| Fixes for Heart Rate Monitor Problems]]. * '''Data Upload.''' The ability to record your workout and store it in a training log such as [[Dailymile]] or [[SportTracks]] is vital. All of the recommended watches here have that ability. I'd strongly advise even a new runner to store their data so that they can look back over the months and years to understand their progress.A watch that can upload to a PC makes recording your workouts much easier.* '''Battery Life.''' How much battery life you need depends on how long you run for. It's best to have a watch that will last quite a bit longer than your longest run. I list the claimed battery life in my table, along with the results of my testing. For my tests, I do everything to maximize battery life without compromising GPS accuracy. That means normal GPS sampling frequency, but no backlight, no map display, and no button presses. I also ensure Bluetooth, WAAS and GLONAS are disabled. I don't test devices that I've had for a while, as the battery tends to degrade over time. * '''Charges On The Run'''. For ultrarunners, one option to use a watch for longer than the built in battery lasts is to charge the watch while running. This involves connecting the cable and carrying a USB battery pack. It's cumbersome, but it can work. A value of "Yes" means that the watch will accept charge while recording and displaying as usual. Some watches have a "yes" with a caveat, such as the display not functioning or difficulty in connecting the cable while wearing the watch. An asterisk after the yes indicates a Garmin device that needs to be set with the USB mode to "Garmin" not "Mass Storage". A value of "no" means that charging is impossible. * '''Altimeter. '''An altimeter will measure the atmospheric pressure and give you altitude. This is more accurate than GPS, but will require calibration to adjust for weather related pressure changes.* '''[[Firstbeat| Training Effect]].''' This is a measure of how hard a training run is as a numeric value of 1.0 to 5.0, based on an analysis of [[Heart Rate Variability]].* '''Heart Rate Variability'''. There is a growing interest in the possibility of using [[Heart Rate Variability]] (HRV) to evaluate training stress. While only one device will display HRV, there are several that will record HRV for later analysis. * '''GPS Pre-cache'''. Some newer watches will download the predicted positions of the GPS satellites for faster initial acquisition. This pre-cache works remarkably well, and the data is usually downloaded automatically when the watch is connected to the internet. However, the data is only valid for a few days, so after that time the device will fall back to the usual approach of scanning for satellites. =Comparison=Here's a table of these features for each of the watches I recommend (all have GPS). {{:Best Running Watch-table}}=GPS Accuracy=[[File:GPS Accuracy.png|none|thumb|600px|An infographic of [[GPS Accuracy]] of running watches.

Only the 310XT and Garmin 610 as few watches can do this. * The GPS is be relied on to lost more accurate than earlier watches, and has a faster startup time. (It uses the SiRFstar III 20 hours with Instafix, one of the latest GPS chipsets)* The housing is fully waterproof (active. I think there are three main approaches to 50m/160ft), so running in the rain is no this problem. :* Connection to a PC is wireless, using a USB adapter# [[Charge On The Run]]. This is less hassle than any of the other options I've tried. * The display is big enough a little cumbersome as you typically have to show four readings. I often display current pacecarry a battery pack and an adapter, average pace for the current lap, average pace for the run and either heart rate or distance. * You can upload courses and display at least have themin your drop bag. This is great when running somewhere unfamiliar. * There are several optional extras for the 310XTNot all watches support [[Charge On The Run]], including the already mentioned footpod and heart rate strap. For cyclists there is also only a speed/cadence sensor and it works subset of them do so with various power sensorsreasonable convenience. * The vibration alert works nicely# Use two watches. I often run with the 310XT set to record a lap every mile, This is also rather inconvenient and it will vibrate as well as beep. ==Cons==* The biggest downside for most people is the price. The watch without any accessories is $250expensive, though you can sometimes get it a little may be able to use to cheaper (Black Friday). However, many of the alternatives are even watches rather than one more expensivewatch. * Some people find For the 310XT to be rather largesecond part of your run, the second watch won't have your full time and it is much larger than distance, so you'll need to make a normal note from the first watchand do some math. (Doing math late in an ultra is as difficult as it sounds. )* The # Extended battery life is good for about 16-20 hours, which is enough for most people. Ultrarunners doing 100 mile or longer races will find this a problem. ** For 24 hour races where A number of watches allow you to reduce the GPS track is not important, you can extend the accuracy to gain greater battery life . This lack of accuracy can be offset by turning off using the GPS receiver and use Stryd Footpod for the footpod. After 12 hours of running I still had 85% first part of the battery leftrace (they claim that Stryd lasts 20 hours. * The heart rate monitoring ) Another approach is not as reliable as to turn the Polar systemsGPS off entirely and rely on a first generation [[Footpod]], though I'm told a new strap is coming that improves thisin which case many watches will last several days. I find that While the Garmin heart rate strap give bad readings far too often, even with accuracy of a conductive gel. There's nothing more annoying first gen [[Footpod]] can be better than seeing your heart rate way too high when GPS, the Footpod does not do so well if you're taking [[Walking Breaks]] or running and having to joggle the strap to get it working againon twisty single track. =Sometimes Cheaper - Garmin 305/205=These watches And some runners will want navigation. I see three main approaches to I wish I could provide, simple, clear cut advice, but unfortunately things are the predecessors not so easy. You'll need to think about how long you'll be running for, the 310XT and features that are quite similar in a number of ways. The 305 has a few extra featuresimportant to you, such as the heart rate monitor and support for a footpodhow much compromise you can live with.
