American beach volleyball duo Misty May-Treanor and Kerri Walsh Jennings have once again taken home gold medals after defeating fellow Americans Jennifer Kessy and April Ross at the 2012 London Olympics Wednesday.

May-Treanor and Walsh have now done the extraordinary. After taking home gold medals in Athens in 2004 and Beijing in 2008, they have now received their third set of gold medals as a team. No other Olympic beach volleyball team, whether men or women, has ever won the gold at three consecutive Olympic Games.

The duo also holds the distinction of being completely undefeated throughout their 21 Olympic Games together. In most of their matches, opponents were not able to win even a single set against the American duo.

Not even their American compatriots could win a set against May Treanor and Walsh. The three-time gold medal champions won the match 21-16, and though Kessy and Ross put up a strong fight, they ultimately went home with the silver.

"It's insane," Walsh told Reuters. "It doesn't feel like it's real. I told Misty when we were getting our medals, 'If I wake up tomorrow and we have to replay this match I'm going to be furious', because it feels like we're in a dream.

"It truly feels surreal. And it didn't feel like that the first two times, for whatever reason. But this is just... it's almost too good to be true."

This is the first Olympic competition for silver medalists Kessy and Ross, who were crowned world champions in 2009. Through they ultimately lost the match to May-Treanor and Walsh, the pair holds a strong amount of respect for this year's champions.

"They are the best team of all time," said Kessy.
