Train like the pros with the Garmin Forerunner 645.
Garmin's Forerunner 645 utilizes a light body with super-tough Gorilla Glass to deliver a light and tough smart watch. It's a perfect fit for any rider who wants to best themselves and keep improving. This premium GPS running/triathlon watch helps you fine-tune your training and recovery to be a better athlete.
The Forerunner 645 GPS running/triathlon watch features a lightweight, comfortable design you’ll be happy to wear all day. It's compatible with Garmin’s line of easy-to-swap QuickFit™ bands. With a band to suit every event, you can easily change from sporty silicone to classic leather and even high-end metal.
If you're looking to up your training program, the 645 will help you monitor your training and recovery so you can better prepare for a race or training cycle. Training status is a new performance monitoring tool that automatically evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching. The new anaerobic training effect metric opens a window of insight to a critical dimension of training, telling you how your training is improving your ability to push the limits. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
