Then, at the appointed time (listed after the break), all you need to do is pop in Kinect Sports and "complete a sprint mini-game while connected to Xbox Live." Make sure not to choose the entire track and field event from the menu or it won't count.
All who download the gamer pic and participate in the record attempt will be rewarded with the Guinness World Records avatar tee (pictured).

Guinness World Record attempt will take place at:
• 6pm UK Saturday April 23
