Forgoing the Nike + iPod Sport Kit, Marshall at Distance Is Love tracks his walking speed, pace, and distance through the Garmin Forerunner 201. With an ergonomic wristband and integrated GPS sensor, the Forerunner helps you reach your training goals by aiming to match - or beat - a virtual partner’s pace and workout distance. Purchasing the Forerunner also gets you access to the Garmin Training Center software, which lets you store and analyze your training data with interactive graphs that chart your speed, pace, or elevation.
