The best Triathlon Watches

LISTING ORDER >> I have tried to list the best & most popular triathlon watches first. Obsolete products are listed towards the END

The watches below record ALL your triathlon data in ONE FILE. A single button press will change them from SWIM to BIKE to RUN. Ask me to stick my neck out and reveal which of these I consider to be the very best triathlon watch, my answer is the Garmin Forerunne 735XT with wrist based Heart Rate. Coming in very closely behind would be, in no particular order, the Suunto Ambit3 Sport, Forerunner 920XT and the Polar V800

Swim, Bike, Run Data

If you bike and run, swim & bike, swim & run, swim, bike & run then you are in the right place. All the watches featured here have the ability to track your progress on land and when swimming. They can time you through the swim, help you control your speed and pace during the ride and pace you along throughout the run. All your transitions are timed and recorded as well. At the end of the session, all the data can be uploaded for a post session review

Please note. If you do NOT need to record a single session across multiple sports and you are happy to STOP one exercise and start a new one when you change sport then please consider the TomTom Runner 2 / or the new Runner 3 (sometimes called the Spark 3)

    Suunto Ambit3 Sport

    ** TOP 3 for TRIATHLON **

    REPLACED by Spartan Sport

    I still regard this product as a top performer. If you don't need the barometric weather functionality of the Ambit3 Peak, but you still want MultiSport support, consider the Ambit3 Sport. Available in several colours including blue, coral, black, white and sapphire. The Suunto Ambit3 Sport is the perfect watch for Triathlon  even though it's been sidelined by the Spartan....

Access to thousands of APPS from the Movescount.com website. Sport displays configurable via Smartphone connection. And best of all... a 30 hour GPS battery life ....

  • A Brief History…

    It all started in 1996. As a sports science student I wanted to promote the use of Heart Rate Monitors in exercise. The business went online in 1999. In 14 years we sold HRM's to over 300,000 customers.

    After a short retail back we're now back with the new online store selling ONLY Polar. We still offer impartial advice & test other heart rate monitor brands. Our aim however, is to introduce you to Polar's products as an alternative to Garmin, Fitbit, Suunto or TomTom.
