Strava

Strava is an American internet service for tracking physical exercise which incorporates social networking features. It started out tracking mostly outdoor cycling and running activities using Global Positioning System (GPS) data, but now incorporates several dozen other exercise types, including indoor activities. Strava uses a freemium model with some features only available in the paid subscription plan. The service was founded in 2009 by Mark Gainey and Michael Horvath, along with co-founders Davis Kitchel, Chris Donahue, Mark Shaw, and Pelle Sommansson, and is based in San Francisco, California.
