It has over 30 different activity profiles that it can track, which now includes triathlons.

Listen to music, audiobooks, podcasts and more on your run. The Forerunner 255 Music allows you to download up to 500 songs, plus playlists from your Spotify, Deezer or Amazon Music accounts (subscription may be required).

You can track your distance, pace, elevation, heart rate and more for each run to help you train better.

Plus, Garmin improved the battery life of the Forerunner 255 Music, so you can train up to 30 hours in GPS mode (up to 6.5 hours with music) or wear it for up to 14 days in smartwatch mode before needing to recharge.

Stay safe on your runs thanks to LiveTrack, which lets friends and family follow your real-time location and view your pre-planned course. Plus, If you feel unsafe or if your watch senses that an incident occurred, the assistance and incident detection features send your location to emergency contacts.

The Garmin Forerunner 255 Music is great to help you maintain a healthy lifestyle—it tracks your steps, stress level, heart rate, sleep and more, so you know how your body is moving and recovering throughout the day. Plus, you can receive emails, texts and alerts right on your watch when paired with your Apple® or Android™ smartphone. You can even respond to texts if you have an Android phone, so you can leave your phone on the charger and enjoy life without worrying about missing an important text or phone call.
