Track Your Swim

The swim-proof Forerunner 310XT is waterproof to a depth of 50 m (164 ft), so you can wear it in the pool, sea or lake to time your swim. With its high-sensitivity GPS receiver and dedicated swim software, 310XT records open water swim distance and average speed. A indispensible training tool for triathletes, this multisport watch records vital metrics for every aspect of the race, from the moment you enter the water to the moment you cross the finish line at the end of the run. And the slim design and flexible wristband mean Forerunner is easy to wear in any conditions.

Transition Effortlessly

When you're ready to jump out of the water and onto the bike, Forerunner 310XT moves easily from wrist to bike with the optional quick release and bike mounts, making the transition between sports effortless. Forerunner 310XT categorises multisport activities in one workout and also can log transition time in the process, letting you analyse the complete performance from start to finish.

Collect Workout Data

Forerunner 310XT tracks your position precisely with GPS satellite data and records time, distance, pace, heart rate (optional) and more. High-sensitivity GPS and HotFix® satellite prediction means it acquires satellites quickly and tracks your movement even near tall buildings or under tree cover. And using innovative ANT+™ wireless technology, Forerunner 310XT connects seamlessly to an optional speed/cadence sensor or power meter (ANT+-enabled third-party power meters) to give you advanced cycling data.

When paired with an optional wireless heart rate monitor, Forerunner 310XT continuously tracks beats per minute and uses heart rate data in advanced calorie computation. Train in a certain heart rate zone to improve fitness and monitor your level of exertion.

You can set pace, speed, distance and heart rate alerts to sound and/or vibrate if you stray from your goal. This is ideal for training in a group, in noisy environments or when wearing headphones.

Run, Sync, Store and Share

Once you’ve logged the miles, innovative ANT+ wireless technology automatically transfers data to your computer when Forerunner 310XT is in range. No cables, no hookups. The data’s just there, ready for you to analyse, categorise and share in our online community, Garmin Connect™. You even can plan workouts on your computer and then send them to your Forerunner.
