But before Jason Kenny gets locked and loaded for round two of his match sprint prizefight, there is a run-off for the minor places in that category and the more serious business of the women's keirin second round.

Great Britain's Becky James - 2013 world champion in the event - goes in the second race alongside Victoria Pendleton's old sparring partner Australian Anna Meares.

Australia's Matthew Glaetzer and Russia's Denis Dmitriev win the first races of their last-eight clashes.

Which means that the spotlight flips back to Jason Kenny and his second face-off with Aussie Patrick Constable.

The man from Bolton leads 1-0 and is looking for the knockout blow...

Italian Gabriele Rossetti came out on top against Sweden's Marcus Svensson to claim gold in the men's skeet shoot. Both delivered faultless performances but the Swede missed the final target to take silver 16-15. 

53-year-old Abdullah Alrashidi, who is an independent athlete as Kuwait isn't recognised by the International Olympic Committee, received a warm reception from the crowd donning an Arsenal shirt after winning bronze in the men's skeet.

Are you sitting at home watching Olympians breaking records here there and everywhere, and starting to feel inadequate? No need! 

Get Inspired has a list of eight world records just begging to be broken - by you.

Callum Skinner hits the after-burners and roars past China's Xu Chao to move 1-0 up in their quarter-final.

Lead from the front, come from behind, different tactics, but the result tends to be the same when it is a British rider.

A big W.

We're going the distance in the second men's semi-final, which can only mean one thing - ear-popping noise from the Argentine contingent in the crowd.

It has been a fabulous match to watch, high quality, momentum changing this way and that. Del Potro has the more vocal fans today, but Nadal the more titles...

The sun is slowly setting, most of the court is now covered in shade. Perfect conditions for what should be a thrilling deciding set. 

Great Britain's Justin Rose has hit a six-under-par round of 65 in the penultimate grouping at the Olympic golf competition.

Two eagles and three birdies for the 2013 US Open champion, and as it stands, he'll start Sunday's fourth and final round one shot clear of the field on 12 under par.

Jason Kenny - defending his individual sprint crown - is first up for Great Britain.

He is taking on Australia's Patrick Constable in their best-of-three quarter-final.

The man from Bolton bursts away to take the first race with space to spare.

Can team-mate Callum Skinner follow suit?

He is up against China Xu Chao.

We are meandering our way slowly towards the mother lode, the main event, the heart of the beast.

This is what is to come tonight.

• Track cycling:Great Britain's quartet will hope to be involved in the women's team pursuit final at 20:53 BST with Becky James aimed at the keirin final at 21:27 BST.

• Athletics: Super Saturday reloaded with Greg Rutherford's long-jump final (00:53 BST), Mo Farah's 10,000m title tilt (01:27 BST) and Jessica Ennis-Hill in the heptathlon finale (03:18 BST)

It is defeat for Chris and Gabby Adcock and the end of their Rio 2016 campaign.

The husband and wife duo have lost 18-21 27-25 21-9 against their Polish opponents.

That means the Commonwealth Games gold medalists, despite having three match points in the match, finish third in their group and miss out on the last eight.

Sweden's Open champion Henrik Stenson uses some down time during the Men's Individual Stroke Play third round to poke an alligator with his golf club.

In case you missed it earlier today, catch up on one Australian footballer's water bottle fail.

The Poles have taken the second game against Chris and Gabby Adcock.

The Adcocks had three match points but it was not to be as their opponents take it 27-25.

It's heartbreak for Nathan Bailey, who won't be taking part in the men's trampolining final.

A second- round score of 59.00 had him sitting in sixth with just four more gymnasts to go, but three of those duly posted higher scores to leave him one place and less than one point outside the top eight, who will return soon to decide the medals.

Gut-punch.

Argentina's Juan Martin del Potro breaks against Spain's Rafael Nadal in the second set to thunderous applause from the crowd.

Great Britain's Justin Rose is now 16 holes into his third round at the men's golf, but his lead is down from two shots to one.

The Briton is six under for the day and 12 under for the tournament, with Henrik Stenson the man just behind him. 

Overnight leader Marcus Fraser is third at nine under, one over par on his third round.

Cheers Steph,

And what better way to start than a picture of British freestyle relay silver medallist James Guy and romantic-comedy titan Matthew McConaughey keeping a healthy degree of separation in a semi-naked semi-soggy selfie?

None. That's what.

I'm off for a pre-velodrome refuel. Here's Mike Henson...
