To celebrate today’s launch, Sports Tracker sets up a competition for you to win a Nokia Lumia 800. I wouldn’t even call it a competition, since you just need to answer a couple of questions. Sports Tracker helps you track your fitness training.

You can download Sports Tracker for Windows Phone at the marketplace. The FREE app is also available for Android, iPhone and Nokia Symbian devices.

Here are the features:

• Tracking
• Distance
• Duration
• Speed
• Average speed and pace
• Max speed
• Energy spent (kCal)
• Training Diary for workout data analysis
• Diary sync to sports-tracker.com service for further analysis
• Sharing of workouts to Facebook, Twitter and the Sports Tracker community

Answer the questions at the Facebook page before December 21st and you’ll be entered to win a Nokia Lumia 800. Good luck!
