What do you do after you win the biggest title in your sport and become a national hero in the process?

If you're Andy Murray, who on Sunday became the first British man to win Wimbledon in 77 years, you party, with very little sleep.

"We got there after midnight and spent a couple of hours there and went home," Murray said today on " Good Morning America," referring to the Wimbledon Championships 2013 Winners Ball he attended last night with his longtime girlfriend, Kim Sears.

"I got about an hour of sleep," he said.

Murray, 26, had much to celebrate after defeating Novak Djokovic in three sets - 6-4, 7-5 and 6-4 - to take home the Wimbledon crown. The last time a British man accomplished the same feat was in 1936, when Queen Elizabeth was just a 10-year-old girl.

"I think that part of it hasn't quite sunk in," Murray said. "I realize that I won Wimbledon yesterday but I think like the magnitude of the win hasn't really sunk in yet."

"The last two or three weeks I've tried to stay away from all of the newspapers, the TVs and everything like that so I'm sure in the next couple of days when I turn the TV back on and watch the news I'll start to understand how big a deal it was," he said.

Murray's fellow Brits understood how big a deal this was just as soon as the championship point was won. The crowd at Centre Court went wild, erupting into a standing ovation as Murray kicked a tennis ball into the stands and dropped to his knees.

Murray's next move was a traditional path taken by Wimbledon champs, heading into the stands to hug and kiss family members and friends, only the tennis champ almost made a big mistake.

Murray was spotted hugging Sears, his girlfriend, and even his coach, Ivan Lendl, but nearly missed thanking his mother, Judy.

"She was actually quite a few rows behind so I didn't actually see her but I heard her shouting when I was on my back down to the court so I thought I better come back and see her," he said. "It would have been pretty good if I had just ignored her but it's probably a good move to go back and see her."

Up next for Murray is the U.S. Open in August in New York City where the Olympic gold medalist will defend his title.

"I'm really looking forward to that," he said of tennis's next Grand Slam. "It was an amazing match last year in New York. I'll take a bit of a break now and get training and try and get myself ready and give it my best shot there."
