Forerunner 310XT

Finally, a GPS-enabled training device that isn't afraid of the water. The rugged Forerunner 310XT is the triathlete's indispensable training tool — a GPS-enabled
trainer that is water-resistant to 164 ft (50 m), tracks data in multiple sport modes and sends it wirelessly to your computer.
This multisport device has up to 20 hours of battery life, tracks distance, pace and heart rate¹ on land, and goes from wrist to bike in seconds.

Track Your Swim

The Forerunner 310XT times your swim in the pool or the lake. And while the GPS signal does not track distance while swimming like it does on land, thanks
to a recent software update, it now accurately estimates open water swim distance and average speed. Simply enable the Swim mode and press start as you begin your swim.
When finished, press the lap button and the 310XT automatically processes a combination of the time and GPS data to compute an estimate of distance covered and average speed while swimming.

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 categorizes multisport activities in one workout and also can 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 rate¹, 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 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. NOTE: Heart rate data is not recorded for swim activities.
