If you're into sport, you'll know that a great part of the excitement lies in competing and exceeding yourself. Strava offers you the resources so you can analyze your results and face them up against those of other users like yourself.
What can I do from the web?
If you've already used Strava's mobile applications to register your physical activity, from the official web you can synchronize the data to analyze them. Another option is to obtain information from a device by Garmin, TomTom, Soleus or others. You even have another alternative: to load the data from a GPX, FIT or TCX file.
Working out is no longer an anonymous activity, as you can share your results on different services: Twitter, Jawbone, MyFitness Pal... Don't hesitate to boast about your progress!
