The Brownlees park up their bike, pull on the plimsolls and Jonathan leads Alistair out onto the 10k run leg.

A straight duel for gold surely.

Daniel Halksworth of Jersey is the closest challenger. Just a shade over a minute behind as he ditches the wheels.

Paul Holland:, external I hope Marc Austin hangs on for a bronze, he deserves it but he might have expended too much there.

Simon King:, external Tremendous effort from Marc Austin to keep up with the Brownlees for so long.

"I just want to give Marc Austin a big hug! When he was a junior we all always looked after and morthered him as he was making the step up to senior level.

"You have to admire Marc because he's put himself on the line to do the best he can, showed real bravery but I think his poor little legs have given up on him. Hopefully he can still get round and put in a good run but a medal might be tough from here."

I wonder what Mama and Papa Brownlee's thought are at a time like this?

Their sons are now off on their own at the front. They exchange words as they swap turns in the lead. But at some point cooperation is going to turn to competition.

Behind them Scotland's Marc Austin has been swallowed up by the chasing pack. He is sitting at the back, steeling his legs for the run.

Jersey's Daniel Halksworth fancies a bit of a cameo though. The 28-year-old - the winner of the 2012 and 2013 Ironman titles - has gone off the front on a solo burst.

BBC Sport's Ollie Williams is attempting to interview an athlete from all 71 nations and territories participating in the Commonwealth Games to create the 71 Club (#71club).

Ghana's first-ever track cyclist, Jedidiah Amoako-Ackah, is the second member of #71club. His wasn't the fastest of times in men's sprint qualifying but it turns out he's not the most experienced man here, to put it mildly.

"I haven't been doing this for long you know - 10 months," he says "I only actually started sprinting in March. I've kind of just dived right into the whole experience and I'm very glad. I've been living in Scotland for 14 years. When I'm speaking to my Scottish friends, my Scottish accent will sort of switch on!"

Make sure you catch Tonight at the Games on BBC One at 22:40 (BST) to hear more from the #71club athletes.

"Big tactics from the Brownlees but maybe Marc Austin has worked so hard and is now paying the price. But the important thing for me is that he went for it. The experience he will have earned means he will be a different athlete after this race, and if he doesn't make it this time I'm sure on another day he will. That young man has been sensational."

It is a family affair at the front. Jonathan and Alistair Brownlee have cracked Marc Austin, breaking clear and opening up a 19 second advantage on the Scot.

Austin is looking weary and New Zealand's Tom Davison and Australia's Ryan Bailie are just 38 seconds behind at the end of the fourth and penultimate bike lap.

His heroic stint in the spotlight could be about to come to an ugly end.

John:, external come on Marc!!!

What a pic John, what a pic.

Ever turned up at a football match without your boots? Or perhaps turned up at the golf course and realised you've forgotten your clubs? Me neither.

But it turns out that even Commonwealth Games athletes are prone to the occasional forgetfulness. Mauritius' Xavier Koenig strolled out to the glass box for his match against England's Nick Matthew, before remembering he needed his racquet. Cue one very embarrassed squash star.

Koenig - a solicitor by trade - was making his Commonwealth bow so perhaps he thought someone carried it in for him. You're not that big time mate...

Marc Austin finished third at both the European Junior Championships and Youth Olympics last year.

Can he hang on here to claim Scotland's first medal of the Games? A crucial 45 minutes in the 20-year-old's life coming up.

Andrew Deans:, external On his website Marc Austin lists his favourite discipline as running. Let's hope so.

Sean Sutton:, external It's no longer a question of if, but which one. Which of the Brownlees will take gold?

The gap has closed. But not by much.

It is down to a minute and one second - four seconds less than it was at the end of the second lap.

Two more laps to go to complete the 40km bike leg. What would be an untouchable advantage for the run? The Brownlees are probably over the hill and gone at anything around a minute.

Scotland's Marc Austin will want a little more to protect him from the strong runners behind.

"It's turning into a bit of a procession for the Brownlee brothers. Marc Austin is hanging on in there and who knows he may come away with a medal here. The Brownlee boys will certainly have been impressed with Marc's performance and be thinking he could be a future 'domestique' for them at the Olympic Games."

New Zealand's Tom Davison, one of the strongest peddlers in the field, has made it up to the main chasing pack and is now cracking the whip to try and drive the pace on.

Has he managed to shut the gap at all? We are about to find out. The leading three - Alistair and Jonathan Brownlee and Scotland's Marc Austin - have just gone through to complete their third lap...

"This is the critical part of the race now. Halfway through the bike stage, the lead of the front three is growing but Marc Austin's legs will be burning. Can he stay up with the Brownlee boys? They are absolutely dominating this race.

"But Austin is not afraid to do his part of the work to try and maintain the lead and is growing in stature with every pedal."

England's Nick Matthew was presented with a shirt after he reached 100 England squash caps with a first-round win over Xavier Koening of Mauritius. "That reception for a first round was incredible," said the world champion. "I was maybe expecting a low-key affair but it was anything but."

Alistair Brownlee is looking confident, bordering on cocky.

As the leaders loop round to race in the opposite direction past the chasing pack, the Englishman gives his pursuers a cheery wave.

He has brother Jonathan and Scottish 20-year-old Marc Austin alongside him and they are still working well together, taking it in turns to take the brunt of the unbroken air at the front of the group.

And the chances are that you could be watching some future Home Nation medallists.

Welshman Robert Weale has won two Commonwealth titles and six medals in total over 28 years. Defending champions Natalie Melmore and Ellen Falkner again play for England, along with Stuart Airey, who took silver in Delhi.

Nine of the 10 players selected by Scotland have played in a combined total of 20 previous Games, with world number one Paul Foster heading the pack.

Think lawn bowls is sedate, grey and a little dull? Think again. Far from being a pastime for the older people of this world, the sport now has a much younger age of participants - the Australian women's squad, for example, has an average age of just 27.

Judge for yourself. You can watch all the action live from the picturesque surroundings of Kelvingrove now. England, Jersey, Guernsey, Wales and Northern Ireland are all playing in the men's triples, while England, Wales, Scotland and Northern Ireland also have teams in the women's fours.
