At North Greenwich Arena: The U.S. women take on rivals Russia, China and Romania for a gold medal in the team gymnastics competition. The U.S., led by Gabby Douglas and Aly Raisman, are the reigning world champions, but the team will need Jordyn Wieber to rebound after she failed to qualify for the all-around competition.

At the Aquatics Centre: Michael Phelps will be a busy swimmer. He'll compete in the 200m butterfly (he won golds in 2008 and '04 in the event) and the 4x200m freestyle relay with rival and teammate Ryan Lochte.
