THE BASICS: Less social site than sport tracker, Connect is an online database for storing routes and parsing workout data collected by Garmin devices. The metrics (speed, distance, heart rate, and power, among others) are some of the most accurate and easiest to manage.
COST: Entry is the price of any Garmin device, like the Forerunner 10 ($130) or Edge 800 ($450).
SOCIAL SKILLS: GarminConnect is less about interaction than simple storage and analysis of data, though you can search through and download other users' activities.
BEST FOR: Archiving and scrutinizing data. Garmin devices aren't cheap, but one payoff is unlimited cloud storage, and given Garmin's hardware arm, you can trust it will be there indefinitely.
