Garmin Forerunner® 310XT GPS Watch w/ Heart Rate Monitor Strap

Finally, a GPS-enabled training device that isn’t afraid of the water. The rugged Forerunner 310 XT is the triathlete’s indispensable training tool — a GPS-enabled, swim-proof trainer that tracks bike and run data and sends it wirelessly to your computer. This multi-sport device has up to 20 hours of battery life, tracks distance, pace and heart rate and goes from wrist to bike in seconds.

Time Your Swim
The swim-proof Forerunner 310 XT is waterproof to a depth of 50 meters, so you can wear it in the pool or the lake to time your swim. And its 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 310 XT moves easily from wrist to bike with the optional quick release and bike mounts, making the transition between sports effortless. Forerunner 310XT categorizes multisport activities in one workout and can also log transition time in the process, so you can analyze your performance from start to finish.

Collect Workout Data
Forerunner 310XT tracks your position precisely with GPS satellite data and records distance, pace, heart rate, power data (from ANT+™-enabled third-party power meters) and more. High-sensitivity GPS and HotFix™ satellite prediction mean Forerunner 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 heart rate monitor, foot pod and cadence sensor.

When paired with the 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.

Run, Sync, Store and Share
Once you’ve logged the miles, innovative ANT+™ wireless technology automatically transfers data to your computer when Forerunner is in range. No cables, no hookups. The data’s just there, ready for you to analyze, categorize and share through our online community, Garmin Connect or our optional Garmin Training Center™ software. You can even plan workouts on your computer and then send them to your Forerunner

Heart rate:
Add a flexible, wireless heart rate monitor to help you make the most out of your training. The digital heart rate monitor continuously tracks heart beats per minute and uses your heart rate for advanced calorie computation, so you know how many calories you’re burning. Train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performance on the same run.
