Whether you're going for a big run in the park on your lunch break or you've decided to sign up for an ultramarathon, triathlons require lots of intense training that will push your body to the limit. If you thought marathon training was hard, this is a whole new level of putting your body through agony.

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.

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, so read on for our top triathlon tech picks to help you be, ahem, tri-umphant.

Garmin Forerunner 935

Best wearable tech for triathlon training

The Garmin Forerunner 935 is a device built for triathletes and serious trainers – a successor to the Forerunner 735XT and a potential upgrade for those with a Forerunner 920XT strapped to their wrist.

Not only do you get the same sports tracking modes, built-in heart rate monitoring and a plethora of metrics to optimise training and aid recovery, it also offers Connect IQ support, notification support and plenty of battery life to help you go the distance.

Essentially, the 935 manages to pack many of the Garmin Fenix 5 features into a slimmer package.

Suunto Spartan Wrist HR

Best wearable tech for triathlon training

Suunto's latest multi-sport watch shares many of its qualities with the Suunto Spartan Sport, except one that's crucial for triathlete training – a heart rate sensor, and it's one of the best optical ones we've used.

This makes tracking multiple sports an even more in-depth experience, with 80 available for you to choose from in total. This list includes the likes of running, trail running, treadmill running, cycling and swimming (open and pool), but there's also a dedicated triathlon option for your perusal.

TomTom Spark 3 Cardio + Music

Best wearable tech for triathlon training

TomTom's updated multi-sport watch retains the built-in music player and still packs QuickGPSFix tech, meaning your location is picked up faster and maintained precisely; a must for keeping a track of your progress.

Real time information, whether you're running, cycling or swimming, is displayed on-screen, while the design also won't weigh your wrist down. It won't supply with you the same detailed metrics as a Garmin, but it's a decent choice for someone who's venturing into the triathlon training world.

And there's a few options within the Spark 3 range to choose from, with the top of the line giving you access to heart rate monitoring, as well as music storage.

Garmin Forerunner 735XT

Best wearable tech for triathlon training

As you may already know, Garmin's XT range is built for those looking for a serious training companion – these are the multi-sport specific devices. Since the release of the bulky 920XT way back when, the company has also worked to reduce the size and bring us the successor, the 735XT.

Despite being small enough to wear day-to-day, the watch crams in a powerful battery, optical heart rate monitoring, all-day activity tracking, smartphone notifications and plenty of training metrics.

Polar V800

The V800's headline feature is its fantastic coaching system, which is ideal if you're just starting out with your triathlon prep. 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.

Wareable verdict: Polar V800 review

Integrated GPS accurately tracks your runs, while pairing it with a heart rate monitor strap means it works when you've hit the pool.

Garmin Vivoactive HR

Much like the TomTom Spark 3, 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 plus 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 add additional data fields and features. With solid battery life, it's definitely one to consider.

Suunto Ambit3

If you don't fancy splashing the cash on the Spartan Ultra or the Spartan Wrist, the Ambit3 is still a great watch for triathletes. It beams all the data it captures from multi-sports directly to a fantastic iPhone companion app all in one log.

Big test: The best swim trackers reviewed and rated

There's a compass, speed, pace and distance tracking and it'll give you an activity based recovery time so you can tell when you should take a rest day. The heart rate monitor can also be used when you're swimming, while the tailored training programmes are great to keep you on track.

VRX MP3 + Personal Trainer

This duo of products gives you an underwater MP3, with Real Coach training tips that will talk you through your swim as you're putting in the laps. You can even build custom workout plans to mix training sessions up.

Best of all, there's a silicone swim case that'll keep everything protected underwater so you can take them for a swim.

SKINS TRI400 Compression Tri Suit

The Skins Dynamic Gradient Compression delivers oxygen faster to your muscles, giving you more power. Recovery time is improved too, as lactic-acid build up is reduced.

The Toray fabric minimises drag, ideal for both the water and road, while integrated UV protection and moisture management make this the perfect fit for hot, sunny days.

    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?

      Suunto Ambiy 3 should be fit your requirement.

    • tomolliehoppe says:

      The new forerunner 735xt is probably your best bet 

    • alexmsp says:

      I wear my garmin fenix 3 hr every day to work, that thing is never off my wrist and I love it.  People around me are starting to use this tech so it's not out of place.
