Garmin Fenix 6s Review; Why This Runner is Obsessed

Garmin Fenix 6s Review

Garmin Fenix 6s Review

I’ve been asked a lot recently about what running watch I would recommend and what to look for when buying your first run watch. For those looking to step up their running distance and pace, are training for a new goal or just want to track their training, a running watch can be a great investment.

Personally I don’t needallthe things in a running watch but there are a couple of factors that are crucial for me;

– long battery life
– accurate built in GPS
– multisports coverage (swimming, cycling, treadmill)
- 但要漂亮(我想穿它每天)

Check out my post onHow to Choose the Right Running Watch For You…

我的first Garmin watch was theForerunner 205. I genuinely think I bought it because Anne and Emily, the first running bloggers I followed, wore them. I had no idea what I was doing when it came to marathon training, and so I bought one (in the SweatShop sale) because I thought Ineededit to be able to train. Up until that point I was using mapmyrun to track my mileage. The watch was huge, it took a long time for GPS to register but the battery life was incredible and it served me well through three marathons before my friend Kerry made me throw it away.

Next up was theGarmin Forerunner 220, this watch was a lot smaller and more feminine than the old Garmin. I had the purple version but it came in a couple of different colours. This watch had a couple of different functions (including cadence) but overall I used it in the same way I had used my Forerunner 205.

I had lusted after the rose gold and white Fenix 3 and was given a chance to borrow one to test it out but the watch itself was so bulky that I just couldn’t get used to it. However when they brought out the smaller, sleeker Rose Gold Fenix 5, I treated myself to it for my 30th birthday present. I loved it and wore it everyday. Garmin gifted my the Fenix 6S last year, honestly I wouldn’t have upgraded if I was buying it myself because my Fenix 5 was still fully functioning. However I do love this watch so much and highly recommend it for those looking for a new running watch, especially if you’re looking for one you can wear as an everyday watch too.

I have the Fenix 6S Sapphire Crystal version ingrey and rose goldand honestly I was drawn to the watch first by how pretty it was. I wear mine everyday, whether I’m running or not. And I even wear it on my belt loop or lanyard when I’m on the wards at work and have to be bare below the elbow.

I find the watch easy to use which is key for this technophobe.

And the GPS is quick to find satellites (I’ve been one of those idiots waiting for GPS to load in the past with my arm in the air lol). I find it works best when you let the GPS reset before you start running, particularly if you’ve travelled away from your usual run route (eg going abroad or racing somewhere new). I do find there’s sometimes a bit of discrepancy between mine and Emma’s Garmin Fenix watches, particularly if I haven’t waited for the GPS to properly load!

All the data uploads to Garmin Connect and Strava (or other apps if you set them up) to track your routes, distances and paces, plus cadence and heart rate.

你可以设置你的锻炼时间间隔上最Garmin的手表(check out my IGTVshowing you how here), meaningmy run/walk是一个容易得多,而无需不断时钟watch. As well as using this for running intervals, you can also use the watch for swimming and cycling intervals too. I loved using my watch last summer while I was triathlon training (and can’t wait for pools to reopen to start swimming again).

Heart Rate Monitor

内置的手腕人力资源监视器并不是那么的完整性le as a chest strap, which you can buy to go with your watch. I find it useful mostly to monitor effort, but also to see when I might need more recovery (and if I’m on the verge of getting ill when my resting and average HR increases).

There’s also a pulse oximeter built into most of the newer Garmin watches to measure saturation of oxygen in the blood. This is particularly useful when travelling to higher altitudes to establish how your body is adapting to altitude.

Battery Life

Anyone else constantly forget to charge their watch, or worse, forget to bring their chargers with them when they travel? I love that the Fenix 6S Pro has a 36 hour GPS battery life and 48 days when you’re using power management battery saver modes.

There is also a version of the watch, the Fenix 6x pro solar, that has essentially a solar panel for solar charging to extend battery life. Sadly my version doesn’t have this but I hope it’s something we’ll see in more running watches in the future!

Sleep Tracker

One of the functions I don’t use is the sleep tracker, mostly because I find it hard to sleep in my watch (and I wear it on my left arm which means I’ve hit Tom with my watch more than once when I’ve tried to monitor my sleep!). I also think that people can get a bit obsessed with sleep tracking but if you like to monitor your rest then you’ll appreciate this feature.

  • Ground Contact Time– The time your foot spends on the ground with each stride.
  • Ground Contact Balance-Symmetry between left and right foot.
  • Vertical Oscillation- 在你的跑步动作“反弹”的程度。万博开户
  • Vertical Ratio– the cost-benefit ratio with stride length.
  • Cadence– Real time cadence stats displayed on your watch.
  • Stride Length- 实时步幅统计显示在您的手表。

The watch calculates your V02 Max which can help determine training pace and race finish predictors (I love how much faith my watch has in me!).



This is designed to help you achieve your target time during training and races – this is essentially a pacer with you to keep you on track. It can be adapted to take elevation into consideration, slowing you down on the uphill and faster on the downhill.

Garmin give a great breakdown of thePerformance Datatheir watches and the Garmin Connect App can give you if you’re a little bit data obsessed. This info can also be great to give a running coach access to if you’re working with one.

Plotting a Route

Whilst I haven’t tried this before, I look forward to utilising the Navigation feature on the watch when I travel again to find a route used by local runners . You can also upload a pre-planned route using Garmin Connect, this can be a run you’ve used before or that others have run using the app.

Incident Detection

For those looking for the safety additions to your Garmin, you can enable ‘Incident Detection’ that allows your Gamin Connect App to send an automated text and email with your name and GPS location to up to three emergency contacts if you’re hurt or in trouble.

A message will appears on your watch and paired phone letting you know that your contacts will be messaged after 30 seconds have elapsed. If you don’t need help then you can cancel the automated emergency message.

Can you listen to music without taking your phone?

Yes, plus podcasts (although I never run without my phone). You can store up to 2000 songs on the Fenix 6S.

What colourways does the Garmin Fenix 6s come in?

I am obsessed with Rose Gold. So I was trying to decide between the Rose Gold White, Grey and Black versions. Ultimately I chose the grey as it was something a little different to my white (which did get a little dirty), and could be worn with non-fitness clothes too. For those that aren’t into the gold, there are black, titanium, leather and orange bands in the Fenix 6 series. Plus you can always switch out the straps if you get bored on the colour and want to mix things up in future.

How big is the screen/watch faces?

I actually have quite wide wrists and small watches look ridiculous on me, however I really like the 42mm screen size option for those with smaller wrists. There’s also a 47mm and 51mm option.


How much does the Fenix 6s cost?

我的在菲尼克斯6S的灰色和玫瑰金版is currently £669.99, with prices starting at£499.99 for other Fenix 6 watches.

What other Garmin watches are similar, but cheaper?

Love the rose gold but don’t want to pay so much? I LOVE my Garmin Fenix 6S but know that it’s a very pricey product. I honestly don’t use all of the functions that this top range watch offers and think that for most runners, middle-range Garmins would do the job just as well as the more expensive products, especially if you’re only using it for running and not for triathlon.

Forerunner 645 –black and rose goldfor £349.The battery life is 14 hours using GPS and up to 7 days when using it on smartwatch mode. (However using the music function is only 6 hours.) I personally prefer the buttons on the Forerunner 645 vs the touchscreen Vivoactive. (It feels more intuitive to use.) This watch also has the Advanced Running Dynamics, more versatility in data screens compared to the Vivoactive 4S. And includes FirstBeat (allowing you to analyse training status and load).

(Vivoactive 4S –white & rose gold要么pink & rose gold为£239。许多朋友ahve此选项,喜欢它。您可以在此触摸屏手表跟踪20个大项,以及课程的运行。万博开户但是它不包括高级跑步动力,ProPace或跟踪公开水域游泳/铁人三项的能万博开户力。你可以存储500首歌曲。电池的寿命是大约与18小时GPS的菲尼克万博真人娱乐斯6的一半。

How does Garmin compare to the Apple Watch?

Whilst I think Apple watches are awesome, personally I don’t think they’re very accurate for tracking your run paces and mileage. I have found the GPS on my Garmin much more reliable than the Apple watches and like that it connects to both Garmin connect app & Strava. You can read my full review ofApple Watch for runners here.

    I use a garmin but also use the nike run app for the guided runs – the distance covered never matches! Which is most likely to be more accurate??

    • 夏洛特

      I would say the Garmin is more likely to be accurate – my Nike was very off when I used it!

    Forerunner 245 needs to be on this page as an alternative. Much cheaper and still does pool swimming and bike. Does incident detection, body battery too. Fenix is extremely expensive, especially if all you are doing is running.

      Thanks, I’ve never tried a 245 but thanks for mentioning it. There are a number of awesome Garmin’s for different price ranges. I used the Forerunner 220 for years and loved it!

    伟大的文章!我已经拥有你的高达菲尼克斯5S提到的所有的Garmins但不6S。我想你没有提到我想到了菲尼克斯是矫枉过正选手的最重要原因。它在63G相比周围41克为Garmin的245或645的重量绝对吨我也睡不着觉它为它留在我的手臂一巨大的凹痕,基本上干扰我的睡眠一样的道理。在运行时我万博开户的胳膊感觉沉重。万博开户运行明智值得注意的是先进的运行动态需要Garmin的胸部心脏率表带以舒适£40至£80。Fenix酒店6S具有相同的运行特点Garmin的64万博开户5音乐或245音乐,我想这是一个个人的事情,但我认为这是一个有点难看又重,没有玫瑰金量可以撤消。电池寿命是惊人的,但因此它应该是在这个重量!GPS的精度难以比拟的,但245个的音乐和菲尼克斯6S已经从一个在645音乐升级的同一个GPS单元。即使是最好的GPS是高达5%不准确或多个特定的设置,如果你真的想你需要一个运行的步速精度。万博开户 As you note apple watch has a limited battery life that means you cannot wear it all day as it needs an overnight charge so can’t track sleep. The 645 and 245 do swimming and cycling too but don’t have a triathlon mode. You didn’t mention the 945 which basically has everything the fenix6s has in a lighter package including the navigation and triathlon functionality.

      I agree the 945 is awesome, this post wasn’t a round up of all Garmin watches, it was just a couple that i like, think are similar in look to the Garmin Fenix 6 and have tried in the past. I personally haven’t had any issues with the weight of the Fenix 5!
