You are there to compete. The preparations are meticulous but now you are resting, nothing is going on and you can get bit bored. That is one of the factors you have to learn to deal with.

But at the same time the Olympic village can be such a a joyous place - and the atmosphere is infectious. Who are the biggest party animals? The Australians. They are loud, brash and fierce competitors.

This was the climax of all last night's festivities as Brazilian marathon runner Vanderlei Cordeiro de Lima set the Olympic cauldron alight.

At the 2004 Games in Athens, De Lima was leading the marathon when he was grabbed by a spectator who ran onto the course.

He ended up third.

Great Britain's judo squad was training at the British School in Rio yesterday. I'm told it was the busiest day to date here with 10 sports wanting to train before heading off to the Opening Ceremony.

Team GB have never won a Judo gold - this lot are determined to change that.

The judo gets under way with the men's -60kg from 14:00 BST - watch out for Britain's Ashley McKenzie.

Jen McIntosh is the first British athlete up at Rio 2016. 

She'll be competing in the women’s 10m air rifle as the Olympic Games get under way in earnest from 12:30 BST.

The Edinburgh-born 25-year-old has already got five Commonwealth medals to her name, and sounds pretty determined to add a few of the Olympic variety...

That men's road race is the headline act for Team GB on this opening day.

Elsewhere London 2012 gold winner Katherine Grainger gets her fifth Olympic Games under way on the water, three-time world champion Adam Peaty is in action in the water and Kyle Edmund hits the fuzz in his tennis opener.

But those lot are all tucked up tight. Local time in Brazil is a little after four in the morning.

A Games like no other. 

This is first time that the Olympic Games have been to South America. And it already looks a little different.

Here are the Great Britain men's road race team stopping off for some fresh coconut juice on a training ride in the hills around Rio.

Beats a brew stop on a windswept January morning in the UK.

They will try to deliver three-time Tour de France top dog Chris Froome to gold from 13:30 BST.

Check. Check. Check. And check.

Opening ceremonies dazzle, but they rarely surprise.

Rio 2016 was opened in a blaze of colour and life last night, but now it is time to go off script.

It is time for glorious unpredictability of sport to take over.

There is nothing quite like it. And if you like sport, there is nothing quite like the Olympics.
