Garmin Forerunner 310XT

The swim-proof Garmin Forerunner 310XT 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 the Garmin Forerunner 310XT is easy to wear in any conditions.
When you're ready to jump out of the water and onto the bike, Garmin Forerunner 310XT moves easily from wrist to bike with the optional quick release and bike mounts, making the transition between sports effortless. The Garmin Forerunner 310XT categorizes multi-sport activities in one workout and can also log transition time in the process, so you can analyze your performance from start to finish.
The Garmin Forerunner 310XT tracks your position precisely with GPS satellite data and records distance, pace, heart rate (optional), power data (from ANT+-enabled third-party power meters) and more. High-sensitivity GPS and HotFix satellite prediction mean the Garmin Forerunner 310XT acquires satellites quickly and tracks your movement even near tall buildings or under tree cover. And using innovative ANT+ wireless technology, Garmin Forerunner 310XT connects seamlessly to an optional heart rate monitor, foot pod and cadence sensor.
When paired with the optional wireless heart rate monitor, Garmin 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.
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.
