Best Running Watch, including Garmin, Polar, & Suunto
This article is a concise guide to the best running watches available today at differing prices and functionality. As well as recommendations for the best watch, I also have a few that are worth considering in spite of their flaws, and some to avoid. For most runners my top choice is the Garmin 310XT, which is great value for money and has all the features you're likely to need. If that's too big and you want something more watch like, then the Garmin 610 is great, and it's often available refurbished at a great price. Also, consider using a Smartphone; if you already have one they are a cheap option and can have outstanding GPS Accuracy. (Note, I have a Garmin 920XT on pre-order and I'm about to start testing the Polar V800.)

- GPS. GPS provides an easy measure of how far you've run, which is critical for your training. While it is possible to map out a run afterwards, this tends to be tedious and is typically less accurate than GPS. However, GPS is not accurate enough to display your current pace. The Garmin 910XT, 310XT and 610 can display current pace from the Foodpod while using GPS for distance.
- GPS Accuracy. I've Analyzed the Accuracy of GPS watches, and I've found that there are wide differences in accuracy. The Garmin 620 and Garmin 10 are especially poor. Interestingly, adding a Footpod to the 310XT improves their accuracy noticeably. I've not tested all the watches yet, but more devices will be added as time allows. (My testing methodology requires me to run 100s of miles with each watch.)
- Weight. None of these devices weigh enough to have a noticeable impact on running performance, but the weight can be noticeable.
- 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 volume in cubic centimeters to give a single number to compare.
- Waterproofing. Even if you don't swim, having good waterproofing is important to prevent your watch being destroyed by the rain or sweat.
- Current pace from a Footpod. A Footpod can be used to provide pace and distance. Displaying pace from the Footpod provides a far more accurate indication of current pace than GPS, which is important for any training program that requires running at a specific pace. Unlike GPS, Footpods need to be calibrated to provide accurate pace/distance, but this is relatively easy. For most runners, once the Footpod is calibrated it will display the right pace across a wide range of paces.
- 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.
- Cadence. A 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 Foodpod or the newer Garmin watches can use the running dynamics heart rate strap. A Cadence alert will help you stay in the right cadence range, and is a useful feature.
- 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.
- 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.
- Navigation. The primary purpose of GPS in these devices is to measure distance, but some of them can also provide navigation. This 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 or a preloaded course. The Motoactv and Fenix 2 can display preloaded maps showing roads and names.
- 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.
2 Not Recommended
These watches have flaws or a price point that makes them unattractive.
2.1 Garmin 405/405CX/410
The Garmin 4xx series watches use a touch sensitive bezel which does not work well with gloves or when wet. The Garmin 410 has an 'improved bezel', but there are still problems. I also see more people struggling at the start of marathons with the 4xx watches than all the other devices combined.
2.2 Nike+ Sportwatch
There is a lot to like about the Nike+ Sportwatch, but it has one weakness that I believe is unacceptable. The software for the Nike+ does not allow you to use the data from your runs in anything other than the Nike web site. A training log is important, and while beginners may not need one, buying a watch that prevents you from accessing your data in the future is too limiting. The Motoactv is a far more capable watch than the Nike+, though it too has some flaws.
2.3 Garmin 305/205
The 305/205 are the earlier generations of Garmin GPS watches, and are getting hard to find. With the price drops of other devices these Garmin watches no longer offer reasonable value for money, though they offer great GPS accuracy if you can find one.
2.4 Adidas Fit Smart
This is a rather strange hybrid device, that I don't recommend as a running watch. It looks like an activity monitor and functions a little like a sports watch, but in reality is neither. The Adidas has the same optical heart rate monitoring used in the TomTom, but this rapidly drains the battery giving only five hours of use, so it not an activity monitor that is worn all the time. It has to pair with a smartphone to provide GPS, makes it more of an advanced smartwatch, adding heart rate monitoring to the display functions (see below).
3 Using a Smartphone
Main article: Running With A Smartphone
Most smartphones have a GPS built in and support various applications that allow them to function as sports watches. These phones can have remarkable levels of GPS Accuracy as well as many other advantages.
