One of my favorite sports is running. Good for me that I can combine IT and sports (while running) with both devices and great sites. As I already made use of a GPS watch for a few years and recently bought a new one (Garmin Forerunner 305), I also wanted to see some results. At motionbased the various aspects of GPS data, sports data, health data and outdoor data are combined.
By uploading your GPS data, motionbased, tracks not only where you have run (google maps, who else) but also what the weather conditions were.
As motionbased is a sort of community, there are more activities to explore, like active forms or training possibilities. But also blogs and setup running groups are possible.
Check out the site and find out where great running (or biking) paths there are to explore.
