A Deep Dive Into The Fitbit Surge

The FitBit Surge is an award winning GPS fitness tracker with BUILT IN heart rate sensor (no chest strap required). The Surge, like all other FitBit’s, is supported by a BRILLIANT APP available for both Android and iPhone.

If you jog, run or cycle and you’re in the market for an accurate GPS activity tracker with the ability to monitor heart rate WITHOUT a chest strap, then the FitBit Surge might be what you’re looking for. The Fitbit Surge has been reviewed by Tristan Haskins aka CardioCritic

  • Pros

  • Cons

Main Features and Functions

  • A 24/7 activity tracker
  • Smartphone Notifications – receive incoming text and call alerts
  • Off the wrist heart rate monitor (no chest strap req’d) – Fitbit PurePulse
  • GPS speed and distance data while running, walking or biking
  • Easy wireless upload of training data to phone (Android or iPhone)
  • Measure the quality of your Sleep monitor

On top of these essential features you get some of Fitbit’s own features, making the Surge that little bit better than the competition

  • SmartTrack – the Surge will record exercise even when you don’t start a session
  • Calories Burnt Data – use the app to compare calories IN versus OUT
  • Compete with your online friends in the 7 Day Step challenge
  • Motivation to Exercise – get Badges for reaching targets

SmartTrack- Automatic Exercise Recognition

Not every exercise session has to be wrapped in lycra or wrestling with a cross trainer. The Surge is all about recording and motivating you to keep active throughout the day. If I decide to take my dog for a lunchtime walk or possibly a light jog around the block, the Surge will automatically detect this exercise and file it away as a WALK or RUN (depending on intensity) No need to press any buttons or commit to any particular workout. Just do it (wrong strapline, sorry Nike).

Smarttack will kick in after 15 minutes of sustained movement. You can, if you want, reduce that to 10 minutes for example. Your exercise will be pigeon holed in to one of six categories

  • Walking
  • Running
  • Outdoor biking
  • Elliptical
  • General Sport. This includes any high movement sport like tennis, netball or football.
  • Aerobic workouk. Anything with a continuous movement pattern such as Zumba® or Boxercise

Sleep Tracking – Quality not just Quantity

The quality of your sleep is almost as important as your activity throughout the day. Ask any top athlete what they do before a competition and they will tell you that they always try to get good sleep.

The body does most of the muscle repairing and growth during the night. To benefit from a hard day’s work then you need a good QUALITY sleep. It’s not about getting 10 hours per night. It’s all about having long, undisturbed deep sleep.

That’s where the Surge comes in handy. It will automatically monitor the duration and the quality of your sleep. It then sends that data to  your smartphone allowing you to review your sleep patterns in easy to understand graphs on the Fitbit dashboard. The Surge also features a silent “vibrate” alarm to help you wake up in the morning fresh and ready for the next day’s training.

Get Fitbit Badges for Achieving Step Goals

As a little kid I always looked forward to going to the DENTIST as,if I was lucky, I’d get a nice little sticker with a crocodile with a big beaming smile. Who doesn’t love a sticker when you’ve been good? The Fitbit APP will reward all your hard work with a collection of BADGES when you reach certain goals. All these little motivational features are what make the Surge so popular. They’re only subtle little gimmicks but they work

Challenge your Friends – 7 Day Steps

What’s better than getting Fitit badges (above)? Rubbing your friends nose in to just how active you have managed to be in the last 7 days. OK, that might be a bit harsh, but connecting with FRIENDS on the Fitbit APP is easy.

Once connected you can see just how hard, or not, your friends have been this last week. Another great motivational feature. Naturally, if you don’t want your Commando Seal brother in law stalking you… you can decline to have them as a Fitbit buddy..

Keep your Calories Balanced – Food Log

Comparison – Fitbit Surge, Blaze & Charge HR

Sizing Chart – get it right.. please

Like many modern fitness bands the Surge comes in a couple of sizes. Getting the wrong size, especially if too big, will give problems getting accurate heart rate as the back of the watch will not site snug on to your wrist. Just use a piece of string to measure your wrist circumference.

Small – 14 to 16cm

Large – 16 – 19.8cm

X.Large – 19.8 to 22.6cm

Top Alternatives

Next Model UP

The Surge has been discontinued. CardioCritic recommends the Blaze as an alternative.

Next Model DOWN

The model below the FitBit Surge is the Charge 2.

Closest Alternative Fitness watches?

The Fitbit Surge is an excellent all-round GPS equipped fitness tracker with built-in heart rate. The closest fitness watches from competitive brands are the Garmin Vivoactive HR, the Garmin Forerunner 35, the Polar M200 and the TomTom Runner 3. All feature built-in GPS and heart rate off the wrist.

They all support smartphone connectivity and notification. The Vivoactive HR is a GPS multisport smartwatch and has the functional flexibility provided by Garmin Connect iQ. My personal favourite for stylish design, ease of use and essential running functionality is the Garmin Forerunner 35.

Polar M200 a user friendly GPS running watch with wrist based HR & activity tracker

Forerunner 35 similar to the Polar M200 but 5 x HR zones – highly recommended

TomTom Runner 3 multisport GPS watch with swim-metrics and built-in music storage

Wearable Tech Running Fans
If you’re in to wearable technology then Android users may want to consider the Polar M600, powered by Android Wear or for users of iPhone the Apple Watch 2 Nike+. Both these watches feature built-in GPS, are swim proof, have wrist based heart rate and can store music on their internal memory for playback via Bluetooth headphones.

Apple Watch Nike+ iPhone connected smartwatch comes with Nike+ Run Club pre-installed


During this review of the Fitbit Surge my admiration for this competent GPS equipped fitness tracker grow. I know I liked it’s design and functionality when it was released, but I didn’t realise just how good it was until the review.

If you’re not in the market for a FULL on GPS sports watch like the Forerunner 35 or Polar M200 then the Fitbit Surge is an sensible candidate. I have awarded the Surge a rating of 4/5 stars as it’s not perfect, but for fans of Fitbit looking for a watch with wrist based heart rate and built-in GPS the Fitbit Surge has it all.
