Thankfully, you don't have to put in the laps and miles completely alone. There's plenty of wearable tech to give you a helping hand during those early morning or lunchtime sessions.

Fitness tips: How to use heart rate training zones

From GPS watches to body suits, we've sifted through the best and worst of the kit to help turn you into a speedy swim-bike-runner.

Here's our top triathlon tech picks to help you be, ahem, tri-umphant.

Garmin Forerunner 920XT

Until we get to spend some more time with the new Forerunner 735XT, the 920XT remains our pick as the go-to Garmin watch for multi sport action.

Wareable verdict: Garmin Forerunner 920XT review

The wetsuit-friendly timepiece tracks your pace, distance and when you dive in to the pool your stroke count and rate, too. If you're willing to spend a little more, you can always consider the Garmin Fenix 3 as well.

The new TomTom sports watch, which now includes a built-in music player, still packs QuickGPSFix tech picks up your location faster and increases accuracy. So your results are much more precise, a must for keeping a track of your progress.

Full review: TomTom Spark Cardio+ Music review

Real time information, whether you're running, cycling or swimming is displayed on the roomy screen while the new slimmer design won't weigh you down either. It won't supply with you the same detailed metrics as a Garmin, but it's a decent choice for someone who's starting to think about venturing into the triathlon training world.

Polar V800

The V800's headline feature is its fantastic coaching system, which is ideal if you're just starting out your triathlon preparation. With the Polar Flow service, you can create tailored profiles for each sport, balance your training and recovery plus analyse even the most minute details.

Garmin Vivoactive HR

Much like the TomTom Spark, the Vivoactive HR could be a a good introduction to someone that's starting to think about venturing into the world of triathlons and wants to track more than one sport.

Wareable verdict: Garmin Vivoactive HR review

There's an optical heart rate monitor on board and GPS with dedicated apps included for cycling, swimming, running and a whole lot more. It also supports Garmin's Connect IQ apps so you can additional data fields and features. With solid battery life, it's definitely one to consider.

    I have been searching for a activity/tri watch for about a year.  However I keep running into two problems.

    1) I need to be able to wear it at work-or I will forget the thing everywhere.

    2) I'm one of those ever so lucky girls with rather dantie wrists.... 

    ....The Garmin Forrunner is huge on my wrist....can't wear it at work... Help?

    I'm on a quest to find a great affordable triathlon smartwatch. Been now testing some watches, including TomTom Multisport Cardio and Adidas FitSmart. Not convinced yet. A quite good and quite cheap is the 820i from GoLife (See Review, but it's without heart rate sensor. Worth a look still.

    I've been on a quest to find an affordable triathlon watch for under 150usd. Hasn't been easy as TomTom Multisport Cardio wasn't good in swimming tracking (no open water tracking, bad pool tracking) and Adidas FitSmart isn't recommended for swimming at all.

    I tested now a 820i model of GoLife which was quite good (Review, but it's missing heart rate sensor. And the display isn't that modern. But it's worth the look if you're looking for a low-budget watch for triathlons!
