Watch Results
Loaded with serious training features, Forerunner 405CX continuously records your time, distance, pace, calories burned and heart rate. Each workout is stored in memory so you can review and analyze the data to see how you've improved. And advanced training features will challenge you to step up your pace--race against Forerunner's Virtual Partner to improve your times, or set up interval workouts without having to circle the track. You can even download recorded courses to compete against previous workouts. To use the watch, simply tap the touch bezel to change screens without fumbling for a button.
Track Heart Rate
Forerunner 405CX comes with a flexible, wireless heart rate monitor to help you make the most out of your training. The digital heart rate monitor continuously tracks heart beats per minute and uses your heart rate for advanced calorie computation, so you know how many calories you're burning. Train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performance on the same run.
Share Workouts Wirelessly
With Forerunner 405CX, you can share your locations, advanced workouts and courses wirelessly with other Forerunner 405 users. Send your favorite workout to your friends to try, or compete against someone else's recorded course. Sharing data is easy: just select "transfer" to send your information to a nearby device.
Run, Sync, Store and Share
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.
Train Year Round
Take your training inside with the versatile Forerunner 405CX and optional wireless accessories. Pair it with an optional foot pod to track your speed, distance and running cadence indoors when GPS signals are unavailable. The wireless foot pod clips onto your laces for easy removal and automatically turns on when you start moving. Or pair your Forerunner with an optional speed/cadence bike sensor to track the speed and distance of your cycling workouts.
