Kerri Walsh and Misty May-Treanor are going to endure a rough path en route to three-peating gold in the 2012 Summer Olympics.
Tough competition such as Brazil's Larissa Franca and Juliana Felisberta are just one example why, as they bested Walsh and May-Treanor for gold at the 2011 World Championships in Rome.
Also, the two-time defending gold-medalists in Olympic beach volleyball are only ranked No. 3 in the Olympic qualification world rankings. Additionally, Walsh and May-Treanor rank No. 4 on the world tour and No. 5 in the technical team rankings.
By that token, let's check out the top five contenders for Walsh and May-Treanor in London.
