Strava

Strava is a fitness tracking service built around a social feed, used by well over a hundred million runners, cyclists, and other endurance athletes. Activities are recorded with the phone app or synced automatically from GPS watches and bike computers, and each one gets a map, pace and heart rate graphs, and elevation data, which friends and followers can see, comment on, and give kudos to, making training a shared activity rather than a solitary log. Strava's segments turn stretches of road or trail into competitive leaderboards where anyone who covers that segment is ranked, and it provides route planning with popularity heatmaps, clubs, challenges, and safety features like live location sharing. For subscribers it adds deeper training analysis including fitness and fatigue trends, pace and power zones, goal tracking, and an AI feature called Athlete Intelligence that summarizes each workout into plain-language insights and trends. Strava also serves as a hub that connects to dozens of other fitness apps and devices. It is free to record and share activities and to use the social features, with a paid subscription unlocking the advanced analytics, route tools, and personalized insights. Strava also publishes an annual report on global movement trends drawn from its billions of logged activities.
