Microsoft has announced its Xbox Summer Stadium promotion that will be running from June 15th to August 12th. The 8-week program will offer a calendar of sports entertainment and gaming events, as well as a season-long tournament with weekly challenges. Of course, Microsoft will be giving away a lot of prizes and will also be attempting to break a Guinness World Record during the promotion.

By playing selected sports games on your Xbox you can train for complete challenges through playing selected titles. Players that participate will be entered into a drawing for a chance to win 4,000 Microsoft points. Games include Forza Motorsport 4, Kinect Sports Season 2, Dance Central 2, and FIFA 12.

Microsoft will be trying to get into the Guinness World Record books again on June 16th at 6PM BST when players have the chance to join thousands of other runners by taking on the 100 meter sprint from Kinect Sports Season 1. The company is trying to create a record with the most engaged in the Kinect 100 meter sprint at one time.

Microsoft will be working with partners to provide streaming sports entertainment for you to watch during the promotion. Of course, you must have an Xbox Live Gold Membership in order to be watching this sports entertainment.

The only down side about this promotion is that (at least for the time being) it appears to be only for those Xbox 360 players in the U.K. so far.
