Track every swim stroke, pedal stroke, and stride with Garmin's Forerunner 910XT. It's water-resistant to nearly 160 feet and it easily changes between swim, bike and run data, also recording transition times so you can analyze your entire workout or race. The swim metrics feature helps you analyze your stroke, efficiency, and intervals. Plus, it's GPS-enabled, so you can precisely track your position and record distance, pace and even power data from ANT+ enabled third-party power meters. And once you’ve logged the miles, your Forerunner wirelessly transfers data to your computer. Garmin's software even lets you plan workouts and upload them to the 910XT to help you take your training to the next level.
