While the queues outside the Olympic Park seem to be the hot topic of discussion, the line at the ticket office is a short one. Joyce Sartori and Franklin Junior from Rio aren't complaining, however, as they've just bought tickets for the boxing and judo.

Below is an official Rio 2016 statement regarding reports of long queues and the reported stopping of security measures at Olympic Park.

"We apologise to all spectators who have had to queue on the first day of competition. We are fully aware of the problem and frustration. 

"We requested that the relevant authorities increase the speed and effectiveness that people can enter the park by requesting that more employees are working on the x ray machines. 

"Following improvements the lines are now back to normal. We appreciate the patience and understanding shown by fans."

“If I were the Hungarians I’d go and buy a Brazilian lottery ticket, because they’ve lucked out massively. They were going to be last but not only have they qualified, they now get a day off tomorrow.”

The Serbian duo take an unwelcome dip at the Lagao in the men's pairs heats, allowing the Hungarians to qualify.

Amazing scenes here as the Serbian pair of Milos Vasic and Nenad Bedik have just capsized. Most of the crowd appeared unaware as it came a lot further down the lagoon. 

The lagoon can get very choppy as it's such a vast expanse of water and the wind can get up quite quickly being so close to the coast. In fact, it was closed for training because of this earlier in the week.

When Yafai bobs and moves, he really is the guv’nor inside the ring.

That's a great way for him to open his account.

A bit of strife for Dutch rider Bauke Mollema as he gets an mechanical and he had to haul a spare bike off the roof of his team car.

Belgium's Greg van Avermaet has also been in trouble after a puncture.

Both men are using up plenty of energy reserves to get back to the peloton.

Up at the front, the same six riders who broke away early on are still clear, although their lead has been whittled down to around five minutes.

Colombia's Jarilson Patano Gomez, Germany's SImon Geschke, Swiss Michael Albasini, Russia's Pavel Kochetkov, Norway's Sven Erik Bystrom and Poland's Michal Kwiatkowski.

Over in the boxing, Great Britain's Galal Yafai unanimous point victory over Cameroon's Simplice Fotsala sees him through to the second round.

The Birmingham boxer's southpaw stance and lightning quick combinations were too much to handle for his Cameroonian opponent.

Some people have been complaining of hour-long queues, which is nothing on Wimbledon. The snaky queues have now shrunk and are moving more rapidly. Some Brazilians weren't happy however, jeering at a lady with a loud speaker. But there was entertainment In the form of Palhaco Tutu, a jovial clown.

Nineteen-year-old American Ginny Thrasher is the first champion of Rio 2016.

Growing up she always wanted to compete at the Olympic Games in figure skating. 

"About the time I started shooting, toward the start of high school, I knew I wasn't going to make it in ice skating. Other than that, I had never thought about the Olympics before" she said. 

She entered the 2016 US Olympic Trials, with the goal of doing her best, not making the Olympic team.   

Turns out her best was the world's best.

It might be quite choppy out on the water but it is getting quite heated, in a literal sense, at Lagoa where the temperature is tipping towards 30 degrees and the main bar under the stands has run out of water before 11am.

There are no problems with sparse crowds here, but as a result the organisers need to improve their drinks supplies tomorrow if they don't want more rowing at the rowing.

They survived. 

The French rode through the water fantastically and controlled the conditions, but our guys struggled with it. But they’re through to the next round.

Great Britain should be better than the Romanian team, and they'll be shocked by how far they are behind the French.

The French boat has absolutely stormed this. Germain Chardin and Dorian Mortellette are clear winners. 

After a bit of a rough start Great Britain's Stewart Inntes and Alan Sinclair come through in second - that's their place in the semi-finals sealed, with Romania third. The Netherlands drop into the repechage.

Britain’s Ashley McKenzie earned his fourth Grand Slam medal in May when he earned bronze in Baku. 

He is 20th in the world rankings though and will have a bit to make up on the medal favourites in the men's -60kg category. 

He is engaged to Automne Pavia of France, the current European champion in the -57kg division.

McKenzie takes on Turkey's Bekir Ozlu in three minutes time in the quarter-finals.

Conditions are still pretty choppy but the British pairing of Stewart Innes and Alan Sinclair are off in search of a place in the next round.

There are four boats - but only the top three make it through to the semi-finals, with last place dropping into the repechage.

This is Felipe Antonio, an auditor from Sao Paolo I met yesterday.

In good English he says rugby sevens being here is "my dream come true." 

He plays the game back in his city and tells me it's popular there, with around 90 teams to play for.

"Rugby sevens in Brazil has grown," he says. "But after the Olympics I think it will go down. We just don't have the sponsors, it's all for football and volleyball."

The peloton are still plugging away but they are not making too much of an impression on the six-strong breakaway.

The leaders are 6;45 clear

There are no British riders up the front. They are starting to lend their elbows to the peloton's pursuit though.
