Here's Michael Whitaker picking up penalties though - and John Whitaker has not fared well either.

So in the showjumping it was a strong start for the defending team champions with GB's Ben Maher on Tic-tac.

Annalise Murphy is out on the Rio waters trying to win Ireland's first sailing medal in 36 years - she began the decisive medal race in third place overall, and is off to a good start in second place at the first mark.

Yeah, not going to plan this. I've got a couple of videos that tell the story - hold the line...

It is tight as we head into the climax of the second game of the men's doubles quarter-final.

Britain's Langridge and Ellis lost the first game but lead 16-15 in the second.

If you missed it earlier, GB's Jack Burnell looked to have won a bronze medal in a confusing, mixed-up finish to the 10km open water swim.

But he was subsequently disqualified for two yellow cards and he pulled no punches in his assessment: "This is meant to be the pinnacle of our sport and there are referees who haven't a clue what they are doing."

Sir Matthew Pinsent has a bit more detail...

One day I will stop taking pictures of people in silly hats, but that day is not today. I'm thinking exhibition, I'm thinking a New York art gallery, I'm thinking big.

Spectators are certainly in a jovial mood, plenty of dancing going on in the fan park. 

Oh, hang on, I recognise the start of that intro, it's the YMCA. I'm sorry, I must stop typing. I can't not dance to this. All together now...

Briton Nethaneel Mitchell-Blake, who qualified for the 200m semi-finals, talking to BBC Sport:

"It was a tough lane but i'm grateful to be here. It's been a good collegiate season (Mitchell-Blake is at theLouisiana State University in the United States) - my coach had a plan. 

"I'm happy and good right now so that's a main thing. It's another round and a chance to show case to Great Britain what I have."

Well, from a GB point of view, that was a decent session of 200m heats.

Adam Gemili, Dan Talbot and Nethaneel Mitchell-Blake all qualify for the semi-finals.

Fastest time of the session goes to Andre de Grasse in 20.09 seconds.

Usain Bolt ran a pedestrian 20.28 and Justin Gatlin only needed a 20.42 to win his heat.

The semis are 02:00 on Thursday morning (or Wednesday night, depending on your outlook).

Serbia have produced an upset in the women's basketball tournament after they knocked out London 2012 bronze medallists Australia in a closely contested game. 

In their first ever Olympic tournament, they beat the three-time silver medallists by 73-71.

Don't we all hate mornings? It turns out we're actually quite alike, Usain and I.

Rio 2016 100m champion Usain Bolt after winning his 200m heat: 

"I'm a little bit tired now. I hate mornings. The 200m is my favourite event so that's why I get nervous. It's a good start and I'm happy."

Oh nicely done Nethaneel. GB's Mitchell-Blake sneaks second with a 20.24secs in his first Olympics and will now line-up in a semi-final.

Canada's Andre de Grasse, bronze medallist in the 100m, win in a season best time of 20.09secs.

The 10th and final heat now. GB's Nethaneel Mitchell-Blake goes in lane one.

Callum Skinner is disqualified for almost colliding with Matthew Baranoski of the United States in the first round of the keirin repechages.

Usain Bolt made a very good start. He then really relaxed around the bend. There was nobody in the field that was going to make it halfway competitive.

This is like an extra day of rest for Bolt. The warm-up probably took more out of him than that race... 

So, it was a 20.28 from Usain Bolt, who decides to play with his shoelaces post-race.

Second and through to the semis is Nigeria's Ejowvokoghene Oduduru in 20.34 seconds.

His was a flat out 20.34 - Bolt's was a cantered 20.28.

China's fourth seeds have taken the first game against against GB's Chris Langridge and Marcus Ellis but more positive signs for the Britons.

They trailed heavily in the early stages but fought back eventually losing 21-14.

Still plenty of hope but, for those asking, defeat and Langridge and Ellis will play in the bronze medal match on Thursday.

Isn't it great to be able to just stroll the last 30 metres...
