The Suunto Ambit3 Sport GPS performance watch for triathlon / multisport has been reviewed by Tristan Haskins aka CardioCritic

Update > In October 2016 Suunto released their new Suunto Spartan Sport GPS multisport watch. If you want the latest and greatest offering from Suunto, then please check the review of the Spartan Sport here. Please note. I still hold this Ambit3 Sport in very high esteem and would recommend it to anyone looking for a good GPS runners watch with Bluetooth connection to iOs & Android smartphone. Apart from the full colour touchscreen of the Spartan Sport there are several features that this Ambit 3 Run has that appear to be missing from the Spartan eg. no Suunto APPS support, running cadence and track back … however, there are loads of new features like improved rest and recovery analysis, recovery time view on watch post training, 80 plus pre-installed sports modes and personal bests ….


Release Date (UK) > February 2015

Product it replaced > Suunto Ambit 2R

Suggested Retail Price (when new) > £199-£249

Replaced by > The Suunto Spartan Sport (Oct 2016)

Quick Summary : If you don’t need the barometric weather functionality of the Ambit3 Peak, but you still want MultiSport support, then please consider this Ambit3 Sport. Available in several colours including blue, coral, black, white and sapphire you are certain to get a watch that looks as good as it performs.

The Ambit3 range of Suunto’s first Bluetooth only wrist computers and they no longer support the previous ANT+ sensors. With a Bluetooth connection to your Smartphone you can download your sessions to Movescount and even set your Ambit3’s display settings. Acting in a similar way to a Smartwatch the Ambit3 will send push notifications when you phone receives phones calls, texts and emails.


MultiSport GPS with Training Load & Recovery Feedback

The human desire to get faster is universal amongst most athletes, at all levels. Whether you are doing the local ParkRun, pushing yourself to your limits on the trail, finding your limits on your bike or punishing yourself in the water, the Ambit3 Sport could be your invaluable training partner. A multisport GPS tool that could help you become the best you can be. Just as importantly as tracking live running, swimming and biking performance is analysing the quality of your sleep and active recovery time.

Swimming Feedback

The Suunto Ambit3 Sport is generally sold (but please check) with the Suunto Smart belt. Just like the Garmin HRM-swim belt, the Smart belt stores the heart rate data from the swim LOCALLY. At the end of the swim, when the signal between watch and HR belt is re-established, the swimming heart rate data is broadcast to the wrist unit. With the Ambit3 Sport and SMART belt you get full swim-metrics plus heart rate feedback. At the time of writing this (Sept 2015) it is only this, the Fenix3, the Polar V800 and the Garmin 902XT TriBundle that have the ability to give heart rate & swim-metrics from the same wrist unit.

Smartphone Connectivity

Suunto are no different to everyone else in that they have an App for iOs and Android phones. The Suunto Movescount App lets you plan your workouts and evens provides voice guidance during your training (should you want them). The Movescount app even lets you can adjust the watch’s settings on the go, then relive and share your experience (depending on available network coverage).

Note – we have ticked YES for this watch with regard to “Virtual Partner”. Although not included in the STANDARD features the user has the ability to install the relevant APP in to the Ambit3. For Virtual Partner download the Ghost Runner APP from Movescount. It’s not exactly the same but it basically allows you to run a chosen distance in a target time, racing against a “ghost runner” to pace you throughout.


Closest Competitor

The product from other brands with the closest functionality to this Ambit3 Sport would be the Polar V800 and the Garmin Forerunner 920XT. Both offer true multisport functionality with multiple disciplines being recorded in one exercise file. Each has it’s own pros and cons over the others and we would, in all honesty, be happy to use any for the duration of a triathlon and the training leading up to it.

Polar V800 as an alternative from Polar as their GPS sports watch for triathlon / multisport athletes

Forerunner 920XT as an alternative from Garmin as their top of the range MultiSport GPS watch

Next model UP

The model up from this one is the Suunto Ambit3 Peak with additional navigation support, weather alerts and barometric pressure sensor for more accurate altitude feedback

Ambit3 Peak with additional navigational functionality

Next model DOWN

The Suunto Ambit2 R would be the model down from this one. They are very similar in operation, style and general functionality. The main difference is that the Ambit2 R does NOT allow for multisport training. The Ambit2 Sport adds multiple sports training pages and the ability to perform a triathlon (or other multi-sport event) in ONE session. By that we man all the training data is stored in one file for post session review in Movescount.
