Get an uninterrupted picture of your daily health and nightly sleep with up to 14 days of battery life in smartwatch mode and up to 30 hours in GPS mode. With its sleek design and 1.7 oz weight, you’ll almost forget you’re wearing Forerunner 255 — even when you’re asleep. Featuring easy-to-use buttons and a silicone band, this watch is ready to wear — and tear — with durable Corning® Gorilla® Glass 3. Receive an overview of your sleep, recovery and training outlook as soon as you wake up — alongside HRV status and weather. You can even customize your report to show you what you want to see. Tap into 30+ built-in activities, including the triathlon and open-water swimming profiles — new to the Forerunner 255 series. For races and brick workouts, transition to the next activity with a single button press. View your entire week of daily suggested workouts, which adapt after every run to match your performance and recovery as well as the races coming up in your Garmin Connect™ smartphone app calendar. To help you plan your race day strategy, this feature offers GPS-based pace guidance for a selected course or distance, so you can tailor your efforts to what’s ahead. When using a Running Dynamics Pod or HRM-Pro monitor, the Forerunner 255 watch measures crucial running metrics such as cadence, stride length, ground contact time and balance, and more — while comparing to others in the Garmin Connect app.
