As thousands of runners relaxed after running more than 26 miles through the streets of London on Sunday night, one Hendon man was strumming the final chords of his world record breaking music marathon.

Georgi Georgiev, 26, performed for 45 hours over the weekend at Mannings pub, in Brent Street.

Starting at 6pm on Friday, the bass-guitarist was allowed just five minutes' rest each hour over the two- day session, and lived off a diet of blended pasta, sugar and beer.

"It was horrible, but I was just about able to keep going," admitted Mr Georgiev, who had to learn a set list of almost 200 songs for the performance, all of which had to be familiar songs. No piece could be repeated within four hours.

"The hardest part was the six hours leading up to the record. I wasn't really there in the head."

Stewards, official witnesses and medics were present throughout, with massages and oxygen being provided each time Mr Georgiev took a break.

Mr Georgiev, who lives above the pub, said it would not have been possible without the musicians who accompanied him.

"It was so important to have the support of the guys on the stage, and the crowd always picked me up.

"I gave probably my best ever performance after I broke the record. I just relaxed and played all the songs I love."

Andrea Samengo, 39, who played lead guitar alongside Mr Georgiev for a total of 21 hours, said: "It was hard work. Georgi didn't miss a note, and for him it's a fantastic achievement and he's going to ooze confidence every time he goes on stage."

Georgi's achievement is yet to be confirmed as a Guinness World Record. Officials plan to pour over hours of video footage and witness statements before ratifying the attempt.
