Garmin Forerunner 745


The Garmin Forerunner 745 is a premium GPS running watch that’s optimized for triathlon training.

Garmin built the Forerunner 745 to track every mile you run, ride and swim. By tapping into GPS, GLONASS or Galileo satellite systems, the 745 gives you accurate distance, pace and time no matter where you are.

But Garmin also enhanced the Forerunner 745 with a host of sensors and monitors. A wrist-based heart rate monitor keeps tabs on how hard you’re pushing, and a pulse ox sensor tracks your blood oxygen to let you know how well you’re sleeping or acclimating to altitude.

To go with the GPS tracking and monitors, Garmin loaded the Forerunner 745 with software to estimate your VO2 max, give you updates on your training load and provide peace of mind with real-time location and safety features. You can also sync up to 500 songs right to your watch for phone-free listening on your run.

With a 5 ATM water rating that seals out open-water waves and surprise rain storms alike, the Garmin Forerunner 745 is a lightweight, durable and stylish smartwatch that’s capable of handling every step of your training.
