After two weeks of intense drama, fun and excitement, you might have been forgiven if you thought the enthusiasm for the Games was dwindling. Think again. People have been queuing for 18 hours in a desperate bid to buy tickets for the remaining few events, mainly he men's 5,000 metres today. Mo-mania has hit town with the home fans keen to see Londoner Mo Farah go for a historic double having already won the 10,000 metres.
One fan from Putney had queued for three days in the hope that he would be able to get his hands on one of these prized tickets. Of the six million seats at these Olympics, tens of thousands still remain for sale on the organisers' official website, many in the high-end price range.
But most of the British public are queuing up outside box office booths set up in strategic areas in the capital for tickets sold by other nations whose allocation from the IOC hasn't been snapped up by their own public. These tickets have to be sold at face value.
One fan has witnessed the most Games in its history - 90-year-old American Harry Nelson who is at his 18th Olympics. The California resident first witnessed the Games in 1932 as a child in Los Angeles. Apart from Berlin, the following year, he has been to every Summer Games since. He was among the few US citizens in Moscow in 1980, defying a presidential order for Americans not to attend.
Asked if he would be going to Rio, Nelson answered: 'At 90 you don't know what tomorrow will bring. I tell youngsters, you've got to make the most of every day.'
