Runners love data. So strap on this GPS-enabled sport watch to track your training and then wirelessly send your data to your computer.
The Forerunner 405 is made by Garmin, best known for their GPS devices. It continuously monitors your time, distance, pace, calories and heart rate (when paired with heart rate monitor). Each run is stored in memory so you can review and analyze the data to see how you’ve improved. You can even download recorded courses to compete against previous workouts or race a virtual partner.
