Garmin's new Forerunner 935 is a top-of-the-line triathlon watch designed for serious athletes and people who deeply care about using training statistics to improve their racing performance when it counts.
The Forerunner 935 is designed for elite athletes who are at the top of their game, and this is reflected in the calibre of technology that this watch boasts. It features a built-in barometer and altimeter to provide elevation changes and monitors your performance so that you are alerted if you are undertraining or overdoing it. Very technical features such as ground contact time balance, stride length, vertical ratio, and even more truly set this watch apart from its competitors and show how it would make the perfect companion to a dedicated athlete.
This watch, like other watches in the Forerunner series, features wrist-based heart rate monitoring and all-day activity tracking such as step count so that you can track your progress all day and even all night. It's waterproof so that you can wear it swimming, and offers both indoor and outdoor options for all three disciplines- swimming, cycling, and running. The multisport features mean you can switch sports at the touch of a button and use it for brick workouts as well as triathlon races.
The battery life on other Garmin watches such as the Forerunner 735XT is a little questionable as it doesn't seem to last as long as you'd expect from a triathlon watch, however on the 935 that definitely isn't an issue. The Forerunner 935 boasts a 2-week battery life when used just as a watch, and up to 24 hours in GPS mode meaning you could complete a full ironman or ultra marathon while tracking and not have to worry about losing your progress.
Weighing in at 49g, this watch is a little heavier than some of its siblings like the 735XT, and the watch face is much larger meaning it is not quite as suitable as an everyday activity tracker or even just as a watch. It has an extra button too which means it's a little more complicated to use, however this just reflects the fact that this watch is not designed for your everyday gym goer and is meant to be used thoroughly and to its full potential by a competitive athlete or coach.
The Garmin Forerunner 935 is an exquisite piece of technology and features advanced training information which is sure to boost the performance of its wearer if used correctly. Its attractive design means it can be worn all day, and the built-in heart rate monitor and step tracker means it even covers the all-day activity tracker market that is so popular at the moment. It's definitely not for the faint hearted and is better suited for serious athletes and prolific competitors in the sport of running, cycling, and triathlon. It loses a few marks from me as it's a little too big to be comfortable all day, and the rubber strap meant I got a sweat rash from continuing to wear it for long periods of time after training. However, the technical information remains unbeatable and very impressive.

The Garmin Forerunner 630 is a fantastic running watch with smart functionality and without the distraction of other sports.
Enhanced Running Metrics
The Garmin 630 is aimed primarily at runners and that’s fine with me; it’s my activity of choice and I’m more than happy with a product dedicated solely to running.
The watch captures performance data exceptionally well when synced with the external heart rate monitor (HRM). Personally, I wouldn’t want to use the watch for running without it. The watch is too good not to make the most of its features and data like vertical oscillation, balance, and ground contact time only come to life when the HRM is used.
Activity and Lifestyle Tracking
The activity tracking feature is an additional bonus. I’ve also added lifestyle to incorporate sleep and inactivity too. When one works in an office and sits at a desk all day it can be far too easy to remain seated and still for hours sometimes. An hourly reminder to move from your watch can have a really positive effect.
The sleep tracking is also a nice touch, especially if you aren’t getting much sleep and want to know just how little you’ve had!
Why Choose Garmin Forerunner 630?
The watch is easy-to-use and can be used straight out of the box without needing instructions. It comes well presented and feels sturdy but pretty light.
Garmin GPS watches seem to be getting faster and faster at locking in on satellites. The 630 tended to take under 20 seconds regardless of location or weather, which is handy as it’s been pretty cold recently! So no waiting around trying to get a satellite lock is a big tick in my book.
I’ve always been happy with GPS mapping with Garmin products and this watch was no different. But where it was different was the additional data the watch recorded and the feedback that it provided. I’ve only recently started getting back into running after a good few months of taking it easy. The feedback the watch gave seemed highly effective and motivational. Notifications such as how long to rest until running again, how much I was improving, as well as providing additional data on oscillation and balance all made my runs that bit more rewarding. I could tell, for instance, that a slight hip discomfort was affecting my running when I reviewed a particular run’s data:
48.5% on the left, and 51.5% on the right.
I suspected that I may have been running slightly unevenly and this was the information I needed to give myself a few additional days off.
Additionally, the battery life is phenomenal when compared to a smartwatch such as an Apple Watch. I got well over a week from a single charge wearing the watch the whole time and using the smart functionality too.
To pair the watch with a smartphone (iPhone in my case) was nice and easy. Again, no need to look up how to do it. Get to the Bluetooth setting on the watch and use the app. Setting up notifications was also nice and easy. The notifications are basic and I would consider them as merely a nice-to-have. It would be unfair to pitch the watch as a smartwatch, it’s an impressive running watch with smart functionality as a bonus.
I really enjoyed my runs being automatically uploaded when I got home without even having to remember. My first reminder that I hadn’t uploaded my run was when I received my first Kudos on Strava! The seamless connection with the watch and smartphone (or Wi-Fi) meant no more having to sync up with a computer.
Once you’ve used the watch for a couple of weeks the features really start to stand out and performance improvement becomes easy to track. I liked being notified during runs that things were looking better from a stats perspective. I found them highly motivating and definitely encouraged me to run that little bit further, faster or both!
I really liked the Garmin 630. It’s a great motivational tool that is comfortable and easy-to-use. The data that you can get from the watch is ideal whether you just like stats or whether you are using data to manage your training and goal tracking.
The touchscreen takes some getting used to but quickly becomes clear why it needs some force when running. It’s great that the watch is waterproof although if worn in the shower it keeps thinking the screen is being touched if the watch is locked.
If you are a keen runner and want a watch that will help you improve or keep you updated on performance with some great data, the Garmin 630 is a perfect choice. It’s clearly aimed at all types of runners and can handle training programmes and various types of runs (e.g. long runs, intervals, etc.). The basic smart functionality is a nice-to-have, but for me would not be the feature that sells the watch. The battery life for a product like this is also amazing.
So if you are serious about running this watch is ideal. I would not recommend it to someone that only goes on the occasional run, but if you are running 3x or more per week and love data, this watch is a real winner.
Review by Andy Puddick
The Garmin Forerunner 235 is designed with a purpose, to bring out the best runner in you.
The watch itself looks more mainstream than most fitness watches, although its plastic strap is a bit of a giveaway. The digital watch face is large and clear measuring 4 cm, with plenty of room for lots of readings to be detailed on the main watch face. The watch's five buttons are streamlined to the watch face but easy to select when needed. Despite its fairly large size, the watch weighs in at just 42g, making it one of Garmin’s lightest watches yet. The watch strap features multiple holes to provide a close fit and despite its large screen does not look as bulky as some of its competitors.
The USB charger features a small bulldog clip, which attaches to the side of the watch face, particularly useful to ensure the watch and charger remain attached even if they get knocked during charging.
Heart Rate Training
Starting a training session is easy: you simply select the start button and can then opt for which type of training you will be doing, from running outdoors or running indoors to cycling. The watch finds your heart rate almost immediately without the need to set up so this is a great feature. It was the same with the GPS, in fact, I found that 9/10 times my watch had already vibrated an alert to tell me GPS was ready before I headed outside. Once in training, there were 5 data fields to scroll through, the main being your heart rate screen, which colour codes your reading to your level of intensity. Your heart rate is presented clearly throughout your workout and I found it to be (for the most part) very effective when worn above the wrist bone. Scroll through for distance, time, pace, heart rate zone and lap readings. These are the automatic fields which the watch sets users up with, however as with almost every feature of this watch, these are customisable so the user can view other data such as cadence or temperature. It’s worth experimenting with the features until you find the ones best suited to your training style, with so many there’s bound to be some you find useful.
Once your workout's complete the watch works it’s magic to estimate the amount of recovery time needed for your body to recuperate from the activity. This is a really useful tool for anyone developing their training routine or even to test the effectiveness of their current habits. By knowing what recovery is required the user can manage their workload accordingly and plan the intensity of their next session to achieve the most benefits from their performance.
When running, users can opt for training intervals or finish time. Training interval workouts are based on distance or time. Wearers can then set their work to rest intervals and for how many repetitions or with an open-ending. This feature is great as it eliminates the need for using a separate app to count your intervals.
By connecting with Garmin Connect, advanced users can enter a training programme into their workout calendar or even download and follow workouts from the Garmin Connect IQ (which has plenty of choices) via the ‘my workouts’ key on the watch itself.
Garmin Connect and Garmin Connect IQ
The Garmin Connect app is simple and easy to use with lots of features to play with. You can check your personal best times, check your health stats, and see how many steps you've done. You can choose which widgets you want displayed on the page and it is fully customisable.
When exploring the many features of the website, you'll notice your options mimic those in the app, but just with more detail, more widgets and more things to customise. The Connect IQ is one of those pages you think you’ll just have a quick look at and could end up losing yourself for hours on end.
The average adult in the UK spends 7-10 hours of their day seated and research has shown it can lead us to an early grave, with official guidelines concluding it's crucial to supplement long durations of sitting with a short burst of activity. Garmin’s move alerts prompt you with a gentle vibration after long periods of inactivity to get up and get moving. A red bar appears and you must move until the bar disappears, a simple concept that could improve your lifespan. I certainly found the vibrations useful as it’s easy to get engrossed in work and forget to add these bursts of short activity, which ultimately improve your wellbeing.
During the initial profiling of the Garmin, your regular sleeping patterns are entered and from then on the watch is able to monitor your sleep and also stop move notifications continuing whilst you’re not awake. The watch automatically detects between light and deep sleep, as well as the total amount of time spent asleep. This is a great feature to help monitor and perhaps improve performance, with sleep being vital to aid mental and physical fatigue and recovery.
If you’ve got the time to master its vast array of data, this watch is almost faultless, providing precise heart rate and so much more. Whilst it is towards the higher price margin for fitness watches retailing at £269.99 on Garmin's website, with this device you get what you pay for. The Forerunner has the quantity of accurate data and the quality of Garmin, global leaders in their field.
Who Are Mio?
Mio Global is a company that specialises in heart rate based activity trackers. Founded in 1999 by Liz Dickinson, Mio Global led the market in wrist-based heart rate monitoring technology before it became a widespread trend in the fitness industry. Mio now boast 5 different products in their range: the Fuse, the Alpha 2, the Slice, the Link, and the Velo. Their latest product, the Mio Slice, introduces Personal Activity Intelligence which you can read more about here.
The Fuse is Mio’s answer to an all-day activity tracker. It records steps, calories, distance, pace, heart rate, and now it also tracks sleep.
The Fuse watch comes in 3 colours: cobalt, crimson, and aqua. This watch doesn’t blend in as a regular watch like the Garmin watches, instead, it sits proudly on your wrist and is quite clearly a fitness band. The flat band design is easy to wear under long sleeves and hugs even a small wrist comfortably. It features small circular holes to allow the skin to breathe which is really important in an activity tracker as it can be the case that after a sweaty workout, you are left with sweat rash under your activity band or watch.
When you purchase the Mio Fuse, inside the box is your watch and its charger, which attaches easily with a little magnetic USB clip. Once charged, you are ready to start tracking with your phone. The battery charge lasts about 7 days including an hour's daily workout tracking. The Fuse connects your data using the Mio GO app. Once downloaded, you set up a profile, entering basic details such as age, gender, weight etc. to ensure the monitor is producing accurate feedback. After completing this easy setup, you need to connect your strap as a known device via Bluetooth. I found that if your phone's Bluetooth is already connected to a lot of other devices, it will struggle to connect, so make sure you switch off any unnecessary Bluetooth connections to enable the band to be easily recognised.
Testing the Heart Rate
When you start training, the Mio Fuse asks you to enter its separate workout mode to enhance the heart rate accuracy. While this may seem a simple request, this has taken me a bit of getting used to. Pressing and holding the Fuse’s centre button will cause the watch to flash ‘FIND’ while it searches for your heart rate. Once it's found your reading, another touch of the centre button will set ‘GO’ and you’re on your way. The difficulty I had was that the buttons are very sensitive and so I had to be careful not to start workouts by mistake. That being said, the buttons are designed so that they only activate when the watch is in a horizontal position to avoid accidental tracking, it just so happens when you're sat at a computer your wrist is also in a horizontal position; but my random one-minute workouts are getting less and less frequent, so I think that comes with practice.
Above is the first workout I completed wearing the Mio Fuse, which was a weights session at the gym. My rep ranges are reasonably high - between 8-12 repetitions - meaning my heart rate should be reasonably steady and within Zone 3 for moderate activity. As you can see, my average heart rate was 123 bpm and I’d usually get a reading of about 130bmp for the same routine from my heart rate chest strap so it is pretty accurate.
I decided to try partnering my Fuse with a HIIT (High Intensity Interval Training) session to see how it coped with the heart rate tracking of a more demanding workout.
Above is a Metafit workout. This class is designed to push your body to the max, using lots of plyometrics and compound bodyweight exercises with swift changes and very little rest between intervals, lasting just 25 minutes. Usually, my chest strap reads my heart rate at about 175 bpm. As you can see above, my average heart rate is 143 bpm with a maximum of 179 bpm. The average heart-rate seems a little low, but when you look in detail at the time frame, it appears to be my warm-up which is dragging the average down.
As you can see, my heart rate sits firmly in Zone 4. Exactly where it should be in the ‘Hard Activity’ category. The Mio Fuse has done well here and met my expectations for performance feedback on this workout. As you can also see from these snapshots, the app allows you to name your exercise. Mio GO suggests a list of activities you can scroll down and if your exercise isn’t listed, you can enter your own name under ‘other’. This is particularly useful for those who do a lot of training to quickly find workouts.
Overall, I have found with most wrist-based heart rate readings that the readings drop slightly when compared to a chest strap, simply due to the nature of the monitor standing more of a chance at being effective when it's strapped right on top of the heart rather than down on a wrist. However with the Mio Fuse, all my heart rate zones are very accurate, the watch monitors the highs and lows of my training effectively and it is the most accurate heart rate readings I have seen from a wrist-based monitor thus far.
The Fuse also has another secret weapon to keep you pushing through your workout: it vibrates. The Fuse keeps you constantly aware of how hard you're working by vibrating as you travel through different training zones, which is a unique feature that no other activity trackers offer. These vibrations are accompanied by a colour-coded flashing light and the colours of the lights match the colours of each of your training zones on the app, so you are constantly being reminded of how you’re doing. The fact that Mio specialises in the heart rate monitoring aspect of activity tracking shines through with this feature.
Is It Waterproof?
The Mio Fuse is water resistant to 30m. Whilst I am yet to take the watch for a swim, it was unphased by my shower and sweaty workouts.
New Feature: Sleep Monitoring
Most activity trackers on the market now track your sleep, so Mio has stayed up-to-date with the rest of the market. The app lets you see the amount of time you spent in bed, the efficiency of your sleep, the percentage of which was light or deep sleep, and your resting heart rate. The watch doesn’t automatically track your sleep, so you do have to put it into sleep mode, but this isn't too much hassle.
Mio Fuse Sleep Monitoring
As you can see, I had an almost perfect night’s rest. The feedback on your resting heart rate can then be used to monitor your level of fitness; there are plenty of online charts to calculate how you're doing for your age and gender. Typically, the lower the resting heart rate, the better, as it suggests the heart is getting bigger and stronger due to exercise and, therefore, it takes fewer beats to pump your blood around the body.
Mio Fuse Sleep Monitoring
It is recommended that adults achieve 7-9 hours sleep for optimal recovery and brain functioning. Although we can survive on less, we give our muscles time to recover, repair and grow during our sleep, so being able to monitor how efficiently you’ve slept is a great training tool for any athlete.
The Mio GO app itself is simple and easy to navigate around. The main page greets you with a dashboard highlighting all your daily activities from steps to workouts and sleep. With a simple touch of any of these activities, you can unlock the full details of your performance. To sync new activities simply drag the screen down and the feed will update. The app was straightforward, uncomplicated and precise, with detailed and poignant feedback for both training and recovery.
As an activity tracker, the Mio Fuse has all the basics we’d expect and would be a good watch with these alone, but the addition of accurate heart rate tracking is a game changer. In addition, Mio is constantly updating the app and the watch's features, so it’s sure to continue improving just as your training does.
The Garmin Forerunner 735XT delivers everything you could want from a triathlon watch and more. It is designed for elite athletes and people who are serious about their training progress, but it is suitable for the more casual exerciser too. It provides wrist-based heart rate monitoring, all-day activity tracking, and will take you from one sport to another with just the touch of a button.
The 735XT is more than just a running watch. It records your stride length, time balance, and more while running (although many of the running metrics features are only available when the watch is paired with a chest-based heart rate monitor), and will calculate your VO2 Max and predict race times based on your training history. It also offers lactate threshold estimates but, again, you will need an additional chest-based heart rate monitor for this which is not included in your £399 purchase of the watch.
The Forerunner 735XT is smart and will connect to your phone seamlessly through Bluetooth to provide notifications from your phone, automatic uploads to Garmin’s online community, and live tracking of your training. Syncing the watch with your phone is very easy and has worked every time without any issues for me. The GPS signal is very strong and the watch links up very quickly so that you can get on with your sport without having to wait around for your watch to be ready.
As a multisport watch, the 735XT is not as advanced as some of its siblings like the 935, but it still provides excellent support. It has a triathlon function so that you can time your transitions and switch between sports with just one press of a button. This feature also translates to duathlons and brick workouts for your training. If you only run, then this watch is perhaps too unnecessarily advanced for you, and you'd be better suited to a Forerunner 235.
The all-day activity tracking is a fantastic bonus feature on this advanced watch. The wrist-based heart rate monitor works all day while you’re wearing it and will provide you with a resting heart rate, recovery heart rate, and a graph of activity over the last 4 hours. This is really useful for heart-rate zone training, especially as the stats provided after your workout will tell you how long you were in each heart rate zone while you were active. The watch also provides you with an estimated VO2 max which is great for serious athletes. Part of the all-day activity tracking also includes step count which can be a great incentive to move more, especially on rest days. The watch also syncs with apps like MyFitnessPal so that your daily calorie burn is automatically taken into account when you track your food for the day.
A Closer Look
The watch itself is light at 41g and the watch face is not as big as some of the other Garmin watches like the 235 or 935, so it is better suited for all-day wear. It has a rubberised strap for comfort, although once you're super sweaty after a tough workout, you don’t really want to keep it on as it gets a bit uncomfortable. The various displays are user-friendly and although the watch has a lot of features, they’re easy to find so you don’t feel like you're missing out on useful training information.
The battery life of this watch could be better, especially as it’s designed to be used for triathlons; I wonder whether it could last a full-length Ironman event.
On the whole, I am so impressed by this watch. Garmin has found the perfect balance between the casual running watch and the advanced athlete's companion. It gives more than its cheaper counterpart the 235 and is more user-friendly than the more advanced 935. It is perfect for serious triathletes but can also comfortably be used by people who may just be getting into the sport or who just like to swim, bike, and run. It has the option of more advanced training stats if you really want to go into them while keeping the useful everyday information at the ready.
