A Deep Dive Into TomTom MultiSport Cardio

This unit was released in 2021 and has been superseded by the Runner 2 with built-in MUSIC storage and activity tracking functionality and again by the Runner 3 / Spark 3 … However, If you don’t want or need activity tracking then this model still offers good value for money as a GPS watch / off the wrist heart rate monitor designed for people who run, bike, swim and gym.

  • Who Is It For?

The TomTom MultiSport Cardio is for the exerciser who wants to know how far, how fast and HOW HARD they are training whether it’s RUNNING, BIKING or SWIMMING. The how far and how fast is calculated by the QuickFix GPS, just like other TomTom GPS watches … however, what makes the MultiSport Cardio different is the BUILT-IN heart rate sensor that takes HR data directly off your wrist.

Main Features and Functions

Having heart rate measured directly off the wrist is brilliant. It’s accurate and 100% trouble free. We’ve used this watch for hours of training and not once have either myself or Louise seen and spurious spikes or glitches in the HR data. With the Runner Cardio gone are the days of having to spit on the back of your HR belt to get a good reading… just pop it on the wrist and you’re good to go. TomTom use the optical HR sensor from the innovative company MioGlobal .They are the clever team behind the strapless heart rate monitoring technology used by the TomTom and now the Garmin Forerunner 225.

There are plenty of great features with this MultiSport GPS watch. As a runner who wears glasses in the day I am particularly fond of an extra large display. I found the high contrast display clear and easy to read in all light conditions. Another favourite feature is the one button control. Unlike other watches with buttons around the outside of the case, the TomTom MultiSport has a simple to use toggle switch. Moving around the functions of the watch is easy and intuitive. Simply press up-down-left-right to move through menus.

The INTERNAL accelerometer is also a great feature. When running indoors on a treadmill you still have access to speed and distance data from a built-in sensor that accurately measures your running performance when no GPS signal is available.

MultiSport Training Pages

See what you want to see relevant to each sport. The training pages are informative and you should be able to see pretty much everything you’d want to see while training. There is the option to have the TOP left and right showing whatever you prefer allowing for some customisation to suit personal preferences.

Strapless Heart Rate Sensor

That’s easy, this is one of the biggest selling points of this GPS runners watch. We love it. It’s been rested cycling, running, walking. It’s been tested by large people with thick wrists and Louise with her slender 15.5cm circumference wrists. No problems at all getting an accurate HR reading.

Quick Fix GPS Technology

The Runner Cardio uses QuickFix GPS technology to ensure a quicker synching of the GPS satellites. Dock it regularly, about every 3 days, and your TomTom will know where the satellites are without the need to search for them.

Race Previous Tracks

After a run you can pop it in your RACE BANK. Next to you run the same route you can compare your current run with past performances. The Runner Cardio shows you where you are compared to the stored RACE. A great way to motivate yourself running the same local circuit.

Next Model UP

This is currently the top of the range for TomTom GPS sports watches. As we’ve said, in our opinion, it’s not a true multisport GPS watch like the Polar V800 or Forerunner 920XT as you cannot change sport in the middle of ONE FILE.. however, for the person who RUNS, BIKES and SWIMS and does NOT need all the data in ONE FILE, then it’s a great option.

Next Model DOWN

The next model down is the TomTom Runner Cardio. It’s pretty much the same watch with the built-in heart rate sensor but WITHOUT the multisport profiles.

Technical Specifications

Sport Specific Training Pages

It’s all very well putting the word MultiSport on a watch in an attempt to gain an new audience but TomTom have come up with a product that is suitable for most people who partake in various disciplines. The most important feature of a MULTISPORT watch is the ability to have sport specific training pages. TomTom have provided a good set of DEFAULT training pages for different sports. The user also has the ability to modify these if necessary. They are not truly customisable, but sufficiently enough.

Is it a TRUE MultiSport watch?

Yes.. but NO! What we mean here is this…. Yes, it does allow the user to select from run, bike, swim, treadmill or freestlye and yes, it also provides sports specific training pages. However, it does NOT allow you to change from ONE sport to another in the same session. Having a Triathlon mode requiring a single button press as transition is entered and exited, moving automatically from swim to cycle to run would be preferred. Unfortunately, as this watch does not adhere to our 3 point MultiSport requirements it is NOT included in the MultiSport section of the website.


MultiSport – ONE BUTTON issues aside (above)

An area that I could see improving is the MySports APP and web area. There’s nothing wrong with it, but it’s not got the level of detail that something like Polar Flow has. I’ve had it crash quite a few times, for example when changing ACCOUNT data from metric to imperial… as it stands MySports APP is stuck in metric when I want miles/min (which is what the watch is displaying)…. It’s not a huge criticism and I am confident it is work in progress.

If possible, it would be great if TomTom could add an ACTIVITY TRACKER. I’m not a watch engineer, but I would imagine that the internal accelerometer that is already inside the unit could be utilised to provide 24/7 activity tracking. It’s not an essential feature but something more and more competitors are adding to their line up including the Polar M400 and Garmin Forerunner 620 and 15. (and now the FR225)

Freestyle Mode, Turn OFF the GPS

I’d like to be able to turn OFF the GPS when in Freestyle mode. I spend quite a bit of time in the gym and the Freestyle mode would be my preferred option for logging those sessions under. At present the only mode WITHOUT GPS is Treadmill… .but I might not be doing any treadmill work. TomTom, please can we have INDOOR training mode with average HR, live HR, calories, duration and that’s about all I need really.
