This looks like a well-paced effort from the Welsh. Could they sneak inside England's time? Nope they are about half a second down.

Australia very much the team to beat mind.

Wales now up. They are without 2016 Olympic gold medal winner Elinor Barker.

It was a brave or reckless start from Canada - take your pick - but they fell apart there. Not knowing your own ability to that level is incredibly unusual. Stunning to be honest. I am positive they could have been around or about if they had ridden to their strengths. What can Wales do against that?

Complete shocker for Canada's women, who blast out of the traps but look like they are cycling through treacle as they ship seven seconds or so in no time at all towards the end of their 4,000m.

Awkward moment as that Games record for Australia is announced as a world record on the big screens in the velodrome...

It all went to plan for Australia, that is for sure. All under control. Australia are way ahead of the pack here - a kilometre an hour faster than the opposition.

Absolutely flying. Australia's women's four of Georgia Baker, Sophie Edwards, Chloe Moran and Maeve Plouffe whizz round in a new Games record of 4:14.605.

That is over five seconds quicker than England's time.

We have just finished the first round of women's rugby sevens matches in Coventry where England's Ellie Boatman was the star with four first-half tries in the 57-0 victory over Sri Lanka.

In the other three games, Fiji beat Scotland 31-12, Australia easily defeated South Africa 38-0 and New Zealand overcame Canada 45-7.

New Zealand will be concerned though after Portia Woodman hobbled off with what looked like a foot injury.

Eight games of men's sevens will now follow in the morning session starting with Australia facing Jamaica.

Like on the Gold Coast four years ago, the triathlon medals will be decided over a fast and furious sprint race, featuring a 750m swim, 20km cycle and 5km run – half the distances of the Olympic format.

The men's race gets going at 11:00 BST, with the women's race going off at 14:30 BST.

Pre-race expectations are that both could turn into one-on-one duels for gold.

England's Alex Yee and New Zealand's Hayden Wilde have carved up the four World Series events so far this season, with two wins each. Yee won silver, 11 seconds ahead of bronze-medallist Wilde at the Tokyo Olympics last summer.

In the women's race England's Georgia Taylor-Brown resumes a rivalry with Bermuda's Olympic champion Flora Duffy. Taylor-Brown leads the world standings, but Duffy took the win in her absence in Hamburg earlier this month.

There was a huge roar as Laura Kenny’s name was announced before England started their team pursuit qualifying campaign. She’s the name they’re here to see!

The crowd might not have realised but her husband Jason Kenny - hidden behind a face mask - was also on the track at the start. Now a coach with England, he helped get the riders’ bikes onto the track and into position.

With all four riders guaranteed a spot in the semi-finals, the qualifying for the women's tandem B sprint is run to determine seedings for the next round.

Australia's Jessica Gallagher and her pilot Caitlin Ward recorded the quickest time of 10.675 seconds, with Scotland's three-time Paralympic champion Aileen McGlynn and pilot Ellie Stone second in 11.145.

England's Sophie Unwin and her pilot Georgia Holt set the third quickest time, with Scotland's Libby Clegg and Jenny Holl bringing up the rear.

Not the result I expected. It didn't look to me like they used their riders to their full strength. Perhaps there is more to come from the team, but that is a lot of time to give away.

England finish almost a second and a half behind. Crikey.

New Zealand rode most of their 4,000m win a three after their Olympic silver medallist in the Keirin, Ellesse Andrews, pulled off.

Laura Kenny is driving England on. This is far from a controlled effort. They are still nearly two seconds off the time set by New Zealand.

No panic showing, but a little bit surprising that after only a kilometre the England team was a second behind the leading time, but they are eating into that now they have settled in.

Great Britain's most successful female Olympic athlete Laura Kenny didn't compete at the 2018 Commonwealth Games, having given birth to her son Albie just eight months before.

But she gets a huge cheer as she leads England's women's team out for the 4,000m team pursuit qualifying.

Eight years after winning points race gold in Glasgow she has her sights set on adding to her Commonwealth haul.

Since winning her fifth and sixth Olympic medals in Tokyo last summer, Kenny had a miscarriage and an ectopic pregnancy, but returned to cycling in April.

England are the favourites for the 4,000m team with the final is due to get going at 16:41 BST.

Just the 30 years since he took gold in the men's individual pursuit at the Barcelona Olympics. We'll have a few recollections from Chris about that shortly.
