THE BASICS: This suite of mobile apps and mapping software is the most robust in the social-fitness category. Users track runs, rides, swims, and hikes via smartphone, GPS, and a broad range of third-party devices, then share route maps with the rest of the community.
COST: Free with advertising, $3 without. Additional functionality ranges from $30 to $100 annually.
SOCIAL SKILLS: A new Courses function rates users on Strava-like segments, though rankings are based on a friendlier system—you earn points not for speed but for how many times you finish.
BEST FOR: Creating and locating new routes. A point-and-search map makes finding routes and activities simple, and data can be shared via Facebook and Twitter.
