Strava has become the benchmark for fitness apps, with over 70 million users worldwide. It tracks a range of activities, from canoeing to rollerblading, but it is particularly good for runners and cyclists. The app is probably best known for its "segments", which are small or sometimes very long sections of road or path, defined and named by users. It means that every time you run, you can measure yourself against your last effort on specific sections, helping you to track your training and fitness.
There’s a basic, free version of Strava, which you can use to track your activities and follow your friends’ efforts. But the paid version – which works out at around £4 per month – gives you access to the segments and leaderboards, so you can discover the all-time fastest "athletes", as well as rankings for gender, age group, people who you follow and more. Strava also lets you analyse a wide range of data, including heart rate, power, and cadence, with #statmaps – colour overlays of your GPS route – helping you understand how your elevation or pace may have changed across a run. Plus, you can use the app to find new routes, explore popular places for runners in your local area and set monthly or weekly milage goals. Whether you’re a serious or social athlete, there’s not much you can’t do. Kudos to Strava for a great app.
