Garmin Forerunner 955

Forerunner 955

Ideal for advanced, data-hungry runners and triathletes

Take your running to new levels and dominate your next race with the help of the new Garmin Forerunner 955 GPS Watch. The newest addition to the industry-leading Forerunner line, the Garmin Forerunner 955 GPS Watch is an invaluable training tool for the devoted runner with new features like Morning reports, race widgets, and daily suggested training plans, all designed to help runners maximise their running efforts and better maintain their overall health. The 900 series indicates the most advanced running and triathlon watches in the Garmin Forerunner line. They offer advanced running dynamics and a lengthy battery life, and can seamlessly track multiple sports such as running, cycling, and swimming, as well as the transitions between them. The Forerunner 955 is an updated version of the Forerunner 945, and if you've been keeping tabs on the latest Garmin technology, you will recognise a lot of the new features from the higher-end Garmin Fenix series.

Forerunner 255 and 255 Music

Ideal for dedicated runners and music enthusiasts

The Forerunner 255 (and 255 Music) builds upon the previous version of the 245, which has quickly become the standard GPS watch for the dedicated runner and track athlete alike. The only difference between the 255 and the 255 Music is the ability to store up to 500 songs directly on your wrist for an additional $70. This makes the 255 Music an ideal watch for runners who love to listen to their favourite songs while training but don't want to carry their phones. Simply sync the watch with a pair of safety-approved Bluetooth headphones, like the SHOKZ OpenRun and SHOKZ OpenMove, and you can leave your phone at home.

Compared to the 955, the 255 foregoes some of the luxuries like preloaded maps, a barometric altimeter, and other elevation-related statistics while offering a more affordable price point. If you aren't planning on using those features anyway, then stick with the Forerunner 255. For most runners, this watch provides everything necessary for daily running and race training.
