Bradley Wiggins marked his victorious win yesterday by raising a glass or two and getting drunk.
The 32-year-old fell off the wagon last night after revealing plans to toast his achievement with a few vodka tonics.
He later posted photos of himself on Twitter enjoying celebratory drinks with friends near St Paul's Cathedral.
He wrote: "Well what a day, blind drunk at the minute and overwhelmed with all the messages. Thank you everyone it's been emotional X."
In one photo he is pictured holding up a drink and making the v for victory sign.
Wiggins' success in the road cycling time-trial came just 10 days after his historic Tour de France win.
After he raced to glory around Hampton Court, he told BBC Three: "I'm just going to get really drunk tonight and have a good think about things."
But after winning gold, an overzealous fan stole his cycling shorts while he showered, ITV News reported.
Wiggins said: "It's only a bit of cycling kit. But you don't expect pilferers to do that in a five-star spa. Sweaty cycling kit is probably on eBay tonight."
His seventh medal takes him one clear of rower Sir Steve Redgrave, who has six, making him the most decorated British Olympian of all-time.
His delight at the conclusion of the 44km race was shared by thousands of Union flag-wielding supporters.
He said: "It's really incredible to win an Olympic gold in your home city.
"When you win in the velodrome there are three or four thousand people cheering. Here, around the streets of London, the noise is just amazing. I don't think anything will top that. It's just been phenomenal."
Wiggins' success has led to calls for him to be knighted by British cycling chief Dave Brailsford and to one bookmaker paying out early on any bets struck on Wiggins winning BBC Sports Personality of the Year.
