The Forerunner series provides outdoor athletes and runners with real-time information about speed, distance, and heart rate all on a single device with an easy to read display. With features like auto-lap/pause/learn/scroll, training assistant tools, various alerts, and Training Center, the Forerunner enabled people to use all of that data to train smarter and more effectively. The Forerunner 305 will serve as the next generation Forerunner family. The Forerunner x05 series will incorporate many of the same great features of the Forerunner x01 series such as ease-of-use, large easy to read display, and software training features while improving other areas of the design to better meet the demands of athletes.
