Time, speed, distance, and heart-rate data can be viewed withtraining software to understand your fitness and the effectiveness of yourworkouts.You can’t use Bodylink for navigation. Your current location doesn’t appearon the watch, and the system doesn’t support tracks and waypoints. (Timexmight add navigation capabilities to future models.) To find different Bodylinkmodels, which retail between $250 and $300, go to www.timex.com.Garmin Forerunner 201Garmin’s Forerunner 201 is a GPS receiver primarily for runners: The receiverlooks like an oversized watch and is designed to wear on your wrist. (TheForerunner 201 is shown in Figure 23-5.) Some of its features include Time (overall and lap), speed (current and average), and distance display Waypoint and track log support Stored workout history Pace and calories-expended information Large, easy-to-read screen Fifteen-hour, rechargeable lithium ion (Li-Ion) battery PC interface and training log softwareUnlike the Timex Bodylink system (which Garmin originally provided the technologyfor), the Forerunner’s GPS receiver is built into the watch: It doesn’trequire a separate armband unit.The Forerunner 201 doesn’t support a heart-rate monitor, but I wouldn’t be toosurprised if future versions will incorporate heart-rate monitor technology.
