Strava tracks running, hiking, cycling, swimming, rock climbing, surfing, yoga and much more. But what makes this social fitness app shine: everyone you can break a sweat with.

What we love: Join others in monthly Challenges, or see where you rank on the app’s leaderboards for popular running trails or bike paths. Each day, Strava’s huge community shares their stats in the app – along with images and kudos.

Quick tip: Strava’s privacy controls allow you to enjoy activities without sharing your location. Adjust your map visibility to hide where you start and end your runs – or hide your routes from others completely.

Meet the creator: Founders Mark Gainey and Michael Horvath met on the Harvard crew team. Inspired by their love of fitness, they created Strava to connect athletes around the world.
